Introduction and Summary Helmut Jenkner
April 21, 2009STScI SM4 Delta Readiness Review5 Purpose and Scope Purpose: Demonstrate STScI Readiness for SM4. Scope: This is a Delta Readiness Review: Builds on SM4 Readiness Review held on September 9 and 10, 2008: Presentations available at All action items from that review have been closed (see list in backup charts). Concentrates on updates, changes and new items, including new work done. Areas with only small changes are summarized in this initial presentation.
Proposal Processing Denise Taylor
April 21, 2009STScI SM4 Delta Readiness Review7 SMOV Proposals 150 proposals (not including ERO and withdrawn props) 35 COS props (164 ext. orb., 111 int. orb.) - All ready. 31 ACS props (38 ext. orb., 493 int. orb.) – All ready 42 WFC3 props (163 ext. orb., 370 int. orb.) - All ready 25 STIS props (21 ext. orb., 174 int. orb.) - All ready 12 NIC props (34 ext. orb., 136 int. orb.) - All ready 3 PCS props (41 ext. orb.) - All ready 2 FGS props (22 ext. orb.) - All ready
April 21, 2009STScI SM4 Delta Readiness Review8 ERO Proposals 8 ERO proposals to be executed after SM4 for 89 orbits (ERO proposal executed 3 orbits on Eta Carina in September 2008 with WFPC2.) All ERO proposals are ready for flight: Three WFC3 ERO One STIS ERO One ACS ERO Three COS ERO
April 21, 2009STScI SM4 Delta Readiness Review9 Cycle 17 Proposal Pool (1) 197 GO proposals including those from HST Cycle 17 TAC, Chandra TAC, and previous HST TACs, for 3627 orbits. 16 SNAP proposals, for 1417 orbits. 24 GTO/COS proposals for 291 orbits. 3 GTO/ACS proposals for 24 orbits. 2 ERS proposals for 214 orbits. 3 GO/PAR proposals for 410 orbits. 103 Calibration proposals for 1088 external orbits, 7069 internal orbits.
April 21, 2009STScI SM4 Delta Readiness Review10 Cycle 17 Proposal Pool (2) Program Coordinators (PCs) are processing observations in the pool: ~ 7000 external and ~7000 internal orbits. Eight calibration proposals still to be submitted. Instrument teams have been reviewing these observations and will have most done before SM4. Remaining will be done according to Long Range Plan schedule. Final processing steps will wait until after SM4, when the ground system is reconfigured for 3 gyro mode. Time-critical Cycle 17 GO observations have been executing in 2-gyro mode since October 2008 (96 orbits so far). After SM4, all remaining Cycle 15, 16 proposals will be re-worked for 3- gyro mode. Remaining NICMOS observations are being switched to another existing or future instrument, when possible to reach scientific goals without NICMOS.
Cycle 17 Long Range Plan David Adler
April 21, 2009STScI SM4 Delta Readiness Review12 Cycle 17 Long Range Plan Cycle 17 Long Range Plan has been rebuilt. Distribution is mostly smooth, with some minor resource conflicts being worked: SM4, SMOV (not in plan) End of SMOV: Aug 17, 2009 End of Cycle 17 Aug 31, 2010 Cycle 17 “tail” orbits/day 11 0
April 21, 2009STScI SM4 Delta Readiness Review13 Cycle 17 Plan: Numbers SMOV, EROs (not included in Cycle 17): ~500 orbits. Cycle 17 Statistics: 380 days in length (8/17/09 - end of SMOV - to 8/31/10). Cycle 17 GO, GTO, cals, etc: ~4550 orbits (100 NIC). Cycle 15/16 carryover: ~600 orbits (500 NIC). Total C15/16/17: ~5150 orbits. Planned Cycle 17 “tail:” ~650 orbits. Expected subscription: 4500 orbits/380 days = 11.8 orb/day ~ 82.6 orbits/week. Slightly above the anticipated rate of 80 orbits/week. Some science may come forward into SMOV if space allows. Some orbits may be dropped if NIC restart is unsuccessful. LRPG is ready for SMOV and Cycle 17.

Freeze Plans HSTMO
April 21, 2009STScI SM4 Delta Readiness Review18 SM4 Freeze Plans HSTP Level Freeze Started on April 13. Extends into SMOV (~few weeks) at discretion of HST Operations Project Manager. Requires HSTP approval for installations while freeze is in effect. HSTMO Level Freeze Started on April 13. Extends into SMOV (~few weeks) at discretion of HSTMO. Requires HSTMO approval for installations while freeze is in effect. Generally will be discussed and approved at SMOV meetings, or via . Some systems will not be affected Must protect systems essential for SM4 and SMOV4… But allow other work to proceed efficiently.
April 21, 2009STScI SM4 Delta Readiness Review20 HSTMO Level Freeze Software covered: APT and TRANS (HST operational versions) Assist SPIKE elements used in APT OPUS, including operational pipeline versions of: CALxxx MultiDrizzle CDBS OMS DADS STSDAS Infrastructure and operating systems for above systems Hardware covered: “SOGS” network DMS hardware (Sunfire 15K, EMC, safestore devices, etc.)
April 21, 2009STScI SM4 Delta Readiness Review21 Other HST Systems Unaffected by freezes: HLA GMS ETCs SPIKE PROMPT
Data Release Policy HSTMO, Science Policies Group
April 21, 2009STScI SM4 Delta Readiness Review23 Data Release Policy Implementation (1) OPB has set initial proprietary period to one year for proposals using either new SIs or serviced modes. ERO and ERS data will remain proprietary until their press release. SMOV and calibration data for COS, WFC3, and the serviced modes will remain proprietary until ERO press release.
April 21, 2009STScI SM4 Delta Readiness Review24 Data Release Policy Implementation (2) Manual process for shortening release dates will continue based on proposal ID, not visit or SI mode GO data taken with new SIs and with serviced modes will be embargoed authorization to access data from proposal will be withheld until the PI agrees not to discuss or present the data publicly until after ERO press releases
April 21, 2009STScI SM4 Delta Readiness Review25 Embargo Agreement Text (as revised per STScI RR AI04) Because NASA has not yet made the first Early Release Observations (EROs) public for the new and serviced instruments, the STScI requires that you agree to abide by the restrictions below before we can make your data accessible to you for retrieval. Once we receive an reply with your acceptance of these restrictions, we will allow you access to your Cycle 17 data. All Guest Observers requesting access to their Cycle 17 data from new and serviced instruments before the NASA ERO press release date must agree to refuse any public discussion or display of these data and/or any scientific results derived from them until after the official NASA ERO press conference. Public discussions include seminars, colloquia, press conferences, lectures, conference posters, website postings, mass media interviews, and journal publications. Do you agree to these terms? Before you distribute these data further to co-investigators or other collaborators working with you on these data, they must agree to these terms also. Matt Mountain Director, Space Telescope Science Institute
NICMOS Readiness Tommy Wiklind, Anton Koekemoer
April 21, 2009STScI SM4 Delta Readiness Review27 NICMOS SMOV4 Readiness NCS re-start attempt during the first week of SMOV: Detailed re-start procedure is being defined. Nominal cool-down time is estimated to be four weeks (previously two weeks). The NICMOS SMOV4 program remains the same as of September Coronagraphic programs placed at the end of the SMOV period. Photometric and grism calibrations will be done as part of a Special Cycle 17 Calibration program. If this NCS re-start attempt is unsuccessful, stand down from all NICMOS activities during SMOV.

April 21, 2009STScI SM4 Delta Readiness Review67 Database SMOV Preparation Environment SMOV4 development utilizes the same methodology that was successfully used for all previous Servicing Missions. Use a separate database and disk space from Operations, but the same machines/servers. spss_sm4 database for SMOV4 development spss database for current SPSS Operations Uses the operational software and tools, but utilizes different PRD/SCIOPSDB and SMS Instructions Allows simultaneous Flight Operations and SMOV development Two environments are isolated The spss_sm4 database is managed in the same way as the SPSS Operations database. This SMOV4 environment is used to: Prepare the SMOV proposals for execution Create the SMGT products Create the SMOV4 representative products Post-SM4 DRM Planning and Scheduling exercise
April 21, 2009STScI SM4 Delta Readiness Review68 Database The Merge SMOV environment, spss_sm4 database, gets merged into the Operations environment, spss database, after rendezvous and berthing occurs. PRD/SCIOPSDB group will audit the merged spss database for correctness OPS will audit the proposals for correctness End-to-end process generally takes about 2 days. This Merge process was successfully tested on September 15 th.

Calibration Pipeline: SSB Software for SMOV Warren Hack SSB/OED
April 21, 2009STScI SM4 Delta Readiness Review87 Calibration Pipeline: SSB STIS: OPRs (zero-exposure time) and (sc2dcorr fix) have been addressed. CALSTIS is ready to support SMOV activities when needed. NICMOS OPRs (pipeline update for BEPCORR and SAACORR) and (SAACLEAN) have been addressed. An update to CALNICB will be delivered as a quick-fix for to address OPR (exposure-time related keywords). Otherwise, NICMOS pipeline calibration software is ready to fully support NICMOS SMOV activities ACS: OPRs (time-dependent distortion keywords) addressed and installed in OPUS CALACS should be ready to support SMOV activities when OPR has been addressed with the quick-fix to OPUS This OPR corrects a problem with CALACS crashing with floating- point CCDGAIN values in the headers of RAW (_raw.fits) ACS files. MultiDrizzle: Updates, primarily to support reprocessing, included: recognizing WFPC2 DQ images in MEF and waiver-FITS format, getting full 64-bit support working under Solaris, processing data in native units or electrons, and fixing a bug processing ACS/WFC data in OTFR. MultiDrizzle remains ready to fully support all ACS data processing needs during SMOV and can be used to test WFC3 distortion calibrations in off-line processing as needed.
April 21, 2009STScI SM4 Delta Readiness Review88 Calibration Pipeline: WFC3 19 OPRs for CALWF3 itself were addressed since the last review. In addition, 7 additional algorithmic changes were also implemented that had no impact on pipeline calibration operations. Highlights of these fixes include: NICMOS CR rejection algorithms now 'tuned' for WFC3 use UVIS calibrations now more robust for use with subarrays and L-FLATS Summary: No issues remain for SMOV pipeline to fully support WFC3 SMOV activities
April 21, 2009STScI SM4 Delta Readiness Review89 Calibration Pipeline: COS 50 OPRs for CALCOS itself have been addressed since the last review. Highlights of these fixes include (but not limited to): Implementation of CSUM file generation by CALCOS Improvements to wavecal processing Proper handling of images with no data, including background regions of subarrays Support of imaging wavecals Improvements to finding a wavecal spectrum Summary: A couple of modes remain unsupported in the pipeline: ACQ image data will not be calibrated yet, wavelength calibration for NUV data needs improvement, and imaging wavecal for TIME-TAG TAGFLASH data in direct imaging mode can not be used to compensate for mirror/mechanism drift yet. A version of CALCOS will be available for off-line use by the COS team during SMOV that will support ACQ image calibration and include improved NUV wavelength calibration. All other modes required for SMOV support have been implemented, tested by the COS team and delivered for use in the pipeline.

April 21, 2009STScI SM4 Delta Readiness Review139 OC Dry Run: Objectives Verify OC operational processes using SMSs, real-time commanding Test all data flow paths and communications Rehearse data reduction and analysis using custom scripts Exercise decision making process Determine timing for analysis, decision making, and producing Ops Requests Verify SMS products for each iteration GSFC, Teledyne and STScI participated GSFC configured EM-3 unit (CEB-R and LVPS-R) and Build-5 WFC in ESTIF Only first 4 of 8 iterations of the OC were simulated + FT as iter 0 Dry Run took place Feb 9 - March 17
April 21, 2009STScI SM4 Delta Readiness Review140 Summary of Results Dry Run was vital for testing analysis software, training analysts, verifying communication and data flow, and exposing problems We verified that we can optimize the parameters by detecting differences in images with different parameter offsets We rehearsed our decision making process by declaring that only 4 iterations were necessary to meet the goals of the OC Issues raised and fixed by Dry Run: - analysis software has been revised/new tasks added - incorrect OPUS keyword issues fixed - Phase II proposal typos and commanding issues fixed - iterations 5 and 6 swapped to allow a full set of visits if we stop early - OC timeline has been extended to allow extra thinking time and to make better use of SMS boundaries
April 21, 2009STScI SM4 Delta Readiness Review141 Revised OC Timeline OC now runs for 37 days compared to original 24 days (Oct launch) Timeline has been extended to provide extra thinking time and to make effective use of SMS boundaries

April 21, 2009STScI SM4 Delta Readiness Review143 Functional Test FT was run as iteration 0 to provide starting point for OC Few issues were discovered - these have now been corrected and FT has been run successfully (review at GSFC on March 18) Issues addressed: Gain change from 2 to 1 1 minute settling time added Subarray Y size changed from odd to even number We will hold final rehearsal for FT next week (April 29th) using data from Dry Run
April 21, 2009STScI SM4 Delta Readiness Review144 Decision points These are the main decision points we will need to pass during the first few weeks of SMOV: 5/24 FPGA data transfer rate 6/18 Removal of last 4 iterations of optimization campaign At end of optimization campaign Clamp and Sample vs Dual slope for SMOV and Science Decision based on overall performance
April 21, 2009STScI SM4 Delta Readiness Review145 If difficulties arise: WFC readout noise is higher than expected at end of OC: Plans in place to review affected ACS Cycle 17 proposals (have been identified by Phase II reviewers) Consider introducing half-speed readout mode in Cycle 18 HRC does not function: All HRC and WFC activities are either separate SMOV proposals or visits - minimal disruption to SMOV plan. Affected Cycle 17 proposals will be reviewed to determine if the science can be executed with other instruments.
April 21, 2009STScI SM4 Delta Readiness Review146 Summary Dry Run has provided excellent test of complex Optimization Campaign and allowed us to detect and resolve various issues We now have all data analysis tools in place to conduct OC, make necessary decisions, and communicate results Data analysis tools are also in place for all the other ACS SMOV proposals Conclusion: The ACS team is ready to support SM4 and SMOV
