Keyes - 5 Mar 2001 Slide 4 of 16 COS Science Team Meeting – STScI Status  COS Thermal Vac Data-Processing Memorandum of Understanding – Defines COS IDT, Ball, and STScI schedule of deliverables – Raw SI data processed through generic conversion by OPUS > Generate FITS files with all proper headers and keyword identifiers, data structures, and formats – No calibration – Catalog data in Hubble Data Archive (HDA) with all necessary searchable keywords and indices – Cost benefit to project; eliminates development of redundant systems – Test images that specify image orientation for all modes prepared by IDT

Keyes - 5 Mar 2001 Slide 6 of 16 COS Exposure Type Summary

Keyes - 5 Mar 2001 Slide 7 of 16 COS Data Format  2-d data: FITS files containing imsets consisting of “science, error, and data quality” images  1-d data and TIME-TAG lists: FITS tables containing fluxes, wavelengths, errors, quality, positions, and other related quantities  Separate files for FUV “A” and “B” detector segments – All associated data (e.g., wavecals, FP-SPLIT components, REPEATOBS components, STIMs) use separate files (unlike STIS)

Keyes - 5 Mar 2001 Slide 8 of 16 Tentative Data File Naming Conventions   Product Suffix Type Contents     Uncalibrated _rawX image Raw counts image   _rtgX table Raw TIME-TAG event list   _asn table Association file   _trl table Trailer file (input)   _jit table   _jif image   _phaX table Pulse-height (FUV ACCUM only)   _rs1X image Stim-pulse 1 (FUV ACCUM only)   _rs2X image Stim-pulse 2 (FUV ACCUM only)   Where X = A, B, or M depending upon segment  

Keyes - 5 Mar 2001 Slide 9 of 16 Data File Naming Conventions (continued)   Product Suffix Type Contents    Calibrated _ctgX table Calibrated TIME-TAG event list   _fltX image Flat-fielded, corrected counts   _flsX image Summed flat-fielded corrected-counts   _x1d table 1-D extracted spectra   _x1s table Summed (combined) 1-D extracted spectra)   _cs1Y image Corrected stim-pulse 1 (FUV ACCUM only)   _cs2Y image Corrected stim-pulse 2 (FUV ACCUM only)   _trl table Trailer file (output)   _spt image Support file (header)   Wavecal exposures produce same calibrated files as science, except no flux calibration applied to the _x1* files (TBD). Dark and flat exposures produce no _x1* files. Acquisition exposures produce no calibrated products.   Where X = A, B, or M depending upon segment   Where Y = A, B depending upon segment

Keyes - 5 Mar 2001 Slide 11 of 16 COS Spectroscopic Mode Data Files   TIME-TAG produces each of the following for each FP-SPLIT=NO science and each wavecal exposure: – – a.) raw photon list (_rtg) per detector segment – – b.) corrected photon list (_ctg) per detector segment – – c.) “observed” count-rate detector image [not retained] per detector segment – – d.) corrected effective-count detector image (_flt) per detector segment – – e.) 1-d extracted spectrum (_x1d) combining all detector segments

Keyes - 5 Mar 2001 Slide 12 of 16 COS Spectroscopic Mode Data Files   TIME-TAG FP-SPLIT=YES exposures: each of the 4 individual component science exposures and all wavecals produce: – – a.) raw photon list (_rtg) per detector segment – – b.) corrected photon list (_ctg) per detector segment – – c.) “observed” count-rate detector image [not retained] per detector segment – – d.) corrected effective-count detector image (_flt) per detector segment – – e.) 1-d extracted spectrum (_x1d) combining all detector segments    and the following is also produced  – – f.) 1-d extracted spectrum summation of _x1d for all 4 individual exposures (_x1s) combining all detector segments   TIME-TAG and REPEATOBS combination is not allowed.

Keyes - 5 Mar 2001 Slide 16 of 16 STScI and the COS Science Team: Looking Ahead   Early Release Observations – – Unique combination of new science and clear public impact > > Demonstrate science capabilities of COS to public audience Traditionally harder for spectrographs Now is the time to start consideration > > Work with STScI OPO ERO Scientist (currently A. Fruchter) and STScI COS instrument team > > Strong NASA HQ and HSTP involvement – – Orbits are in addition to GTO allocation – – e.g., ACS presently developing target list > > Must consider contingencies, SMOV timeline
