1. L. NExScI Operational Readiness Rafael Millan-Gabet Project Scientist, NExScI & Mihseh Kong, NExScI Software Engineer David Imel, IPAC & NExScI Manager Chas Beichman, NExScI Director

2. NExScI Compliance This presentation discusses NexScI readiness to assume responsibility for the archive Relationship to ORR Success Criteria: Satisfies requirement for NExScI to perform processing and archiving of LBTI-produced data Concerns: None Liens: None L-2

3. NExScI Responsibilities (1/3) (PLRA 2014 Section 3.1.3) NExScI shall be responsible for 1.Developing common formats for data products and coordinating with UA to archive data products: a.Interface with UA to receive NASA LBTI data b.Archive the NASA LBTI data at NExScI c.Provide interface for science community access to the archived data d.Monitor data product quality assessments conducted by UA as a service to observers L-3 All part of the archive service: Developed FITS file formats and keywords for LBTI nulling data Automatic data transfers and ingestion Automatic implementation of periods of exclusive data use and public release Web interface to the archive as well as scripted data access HTML summary tables and browse plots

4. NExScI Responsibilities (2/3) (PLRA 2014 Section 3.1.3) NExScI shall be responsible for 2.Selecting HOSTS Science Team members: a.Prepare call for proposals b.Conduct peer review c.Select proposals d.Manage science deliverables L-4 Call for proposals issued in Feb 2012 and selections announced in June 2012 Followed standard peer-review and selection procedures LBTI Project PI (UA) and NASA Project Scientist at NExScI co-lead the HOSTS Science Team Defined a set of 6 deliverables for the Science Team Main ST activities to date: o Monthly telecons + focused telecons (e.g., on the analysis pipeline) o Participation in observing runs o Developed target list (Weinberger et al. ApJ, 2015) o Developed exozodi model (Kennedy et al. ApJ, 2015) o Developed quantitative mission success criteria (Mennesson) DeliverableDue DateComment Preliminary target list9/2014Published paper Weinberger et al., ApJ, 2015 Final target list3/2015Tied to start of operations Report on data calibration methods5/2016After 1 year of experience with the data Report on interpretation and implications for exo-Earth imaging 9/2015 9/2016 9/2017 Incremental releases Final report and plans for publications3/2018

5. NExScI Responsibilities (3/3) (PLRA 2014 Section 3.1.3) NExScI shall be responsible for 3.Providing oversight and guidance to the ExEPO to protect the LBTI’s science objectives and implement NASA HQ policies L-5 NExScI shall be responsible for 4.Providing management oversight of LBTI during the Operations Phase: a.Generate monthly report of science and operations status b.Provide point of contact to UA and ExEPO for resolution of issues and concerns The Project Scientist at NExScI provides these functions for ExEP and HQ NExScI is prepared to assume management oversight functions Plan is to transition at the end of the Science Validation Phase

6. Science Data Management (PLRA 2014 Section 3.4) Addresses archival obligations and data rights for Commissioning data HOSTS HOSTS/LEECH Non-NASA users L-6 Periods of exclusive data use are implemented in the archive, data goes public when they expire Note: HOSTS/LEECH periods of exclusive data use same as for HOSTS Consistent with these obligations, the current version of the archive supports LBTI nulling data Small additional archive development needed to support LEECH data planned for FY16 o If LMIRCam data are needed to mitigate PWV, this task may be de-scoped, or replaced with modifications needed to support the new ancillary data for nulling, if needed

7. Data Rights Implementation L-7 Project ID associated with each observation at the observatory via the Observe Web tool Project ID keyword in header of each Level-0 image; then propagated to L1/L2 files by the pipeline

8. Data Requirements (PLRA 2014 Section 4.2) Addresses data archiving and public distribution obligations described before, plus types of data and timeliness of transfers and archive ingestions: All scientific data generated by the NASA HOSTS survey shall be provided from the LBTI observatory to NExScI for archiving and distribution. An instrument data management plan shall be developed by NExScI and UA to address the total activity associated with the flow of NASA science data, from planning through acquisition, processing, data product generation, and validation, to archiving and preservation. NExScI shall develop common formats and coordinate archiving of data with UA. NExScI shall provide an interface to UA to receive NASA LBTI data. NExScI shall provide a link to the archived data for distribution to the various observers for calibration and analysis. Three types of data products shall be archived; the delivery timescales in each case are appropriate to the needs of the HOSTS survey: 1.Level 0: Merged raw images; delivered from the observatory to NExScI within 72 hrs of observation 2.Level 1: Internally calibrated science data, delivered from the observatory to NExScI within 20 work days of observation. Internally calibrated data consists of: cleaned Level 0 images (dark subtracted, bad pixels removed, flat fielded, background subtracted) and files containing derived quantities (null and stellar fluxes, associated errors, diagnostic quantities) 3.Level 2: Externally calibrated science data, delivered from the observatory to NExScI within 40 work days of observation. Externally calibrated data files contain fully calibrated nulls and associated errors (effects of instrument’s transfer function removed), and result from processing multiple Level 1 files obtained on the target star and its calibrator stars. L-8 Data Management Plan: delivered and in signature cycle (NExScI, UA, JPL, HQ) The data pipeline (UA) automatically takes Level 0 data and outputs the Level-1 and -2 products as described above Detailed data formats documented in ICD and documentation for archive users Demonstrated automatic data transfers and archive ingestion for the three levels of data, and under the required times, on several occasions during the commissioning phase
