Below are potential SIS's that interface with Instrumental Calibration and Frame Co-addition only. Some are TBD as they depend on the details of processing. Some are already written: WSDC D-I005: pre-flight calibration receivables (ICAL input) WSDC D-I101: frame mask-bit definitions (ICAL output) WSDC D-I102: refined WCS/distortion/QA information (AWAIC input) WSDC D-I105: level-1 frame QA metrics and diagnostics (ICAL output) WSDC D-I106: ingest / level-0 frame pixel statistics (ICAL input) WSDC D-I121: level-3 (Atlas Image) QA metadata (frame co-adder output) Inputs to Instrumental Calibration (needed to support processing): ------------------------------------------------------------------ -Metadata/keywords to level-0 FITS headers from ingest. -Specific H/K and PEF information to level-0 FITS headers or other to support dynamic calibration creation and application. -QA metrics on level-0 frames to warn of noisy, corrupt, radhit infested data. Written (WSDC D-I106). -Format specifications for pre-flight calibration receivables. Written (WSDC D-I005). Outputs from Instrumental Calibration (interface with downstream modules): -------------------------------------------------------------------------- -Instrumentally calibration frames (level-1a-int), format and content. -Corresponding uncertainty frames (level-1a-unc), format and content. -Corresponding mask frames (level-1a-msk), format and content. Mask bit-definitions for numerous downstream modules. Written (WSDC D-I101). -QA diagnostics/metrics/plots for QA subsystem. Written (WSDC D-I105). -FPG/metadata specifications and Science Team concurrence. (to propagate to level-1b's + archive) Inputs to Frame Co-addition (needed to support processing): ----------------------------------------------------------- -Refined WCS and distortion information to level-1b FITS headers. Source: PREX wrappers. Written (WSDC D-I102). -QA metrics from PREX processing on refined pointing quality/accuracy. If frame has no/bad ICRS solution, don't include in co-add. Outputs from Frame Co-addition (interface with downstream modules): ------------------------------------------------------------------- -level-2a single-frame distortion corrected and interpolated products: intensity, coverage and uncertainty images. -Level-3 (pre-FPG) Atlas Image products: intensity, coverage and uncertainty images. -QA diagnostics/metrics/plots for QA subsystem. Written (WSDC D-I121). -FPG/metadata specifications and Science Team concurrence (to propagate to archive). Written informally. -Specifications to support WISE image/pixel server -- F.
