OTFR (On-The-Fly Reprocessing)
  • Science data requested from the archive are reprocessed from the pod file (level 1A data)
    • Provides HST data user with optimal product at time of retrieval
      • All calibration updates, bug fixes, and new software features and algorithms are applied to retrieved data at retrieval time
    • OTFR pipeline uses the exact same code as the pre-archive science data processing
      • No added software development and maintenance costs
      • No science instrument-specific code developed for OTFR beyond what is necessary for initial data processing
    • Adds negligible time for retrievals
    • Same operator interface for both pre-archive and OTFR pipelines

OTFR
  • Changes for WFC3? – almost none
    • ASCII templates for existing instrument processing will be copied and altered to reflect the WFC3 processing locations on disk, and the names of the pipeline processes.
    • New instrument implies
      • No keyword repairs yet
      • No special processing cases yet
