Epics

  • VLA Calibration Improvement: Improvements to the flagging heuristics for system and RFI Issues.
    • RFI heuristics for VLA PI pipeline will be modified - moving toward VLASS or VLASS-derived
    • bad deformatter flagging should gracefully recover from bad deformatter on refant
    • Heuristic changes for bad deformatter identification
    • proper multi-band support
      • allow different min/max solints per band
      • allow different bandpass calibrators per band
    • API plot should appear in weblog
    • gaintable flagging of final gaintables based on statistics (do within final cals?)
      • heuristics need to be defined
    • Fluxboot 2 display refinements (PIPE-319, PIPE-426)
    • Fluxboot fitorder determined when different gain calibrators used for different bands
    • Antenna pointing solutions in weblog
    • observing log in weblog
    • flagging summary per stage (SRDP-411)
    • AQUA Report needs to be finished (SRDP-194, CASR-263, CASR-358)

  • VLA Spectral Line Calibration: Modifications to the system to support Spectral Line science with the VLA.
    • per-baseband delay capability should be implemented
    • ability to use spw-mapping per baseband for final gain calibration in low S/N regime (mixed spw setups)
      • pipeline should use fluxboot2 results to determine if gain calibration on individual spws will have too low S/N
    • switched power weights (CASR-476)
    • mstransform hanning smooth pass through (CASR-357)
    • SPW intents and processing options need to be passed from RCT/OPT to pipeline
      • SDM option
      • PPR option
        • Intents : Spectral Line or Continuum
        • Processing Options: Hanning smooth, RFI Flagging, Statwt

  • VLA Imaging Pipeline: Initial version of VLA Imaging pipeline targeting Ku-band and above
    • continuum-only
    • Use nsigma threshhold
      • test automasking or not
    • X-band and higher frequency

  • ALMA PI Driven Imaging: Additional options in the pipeline and interface
  • Improved Download Support: Cutouts for images and data selection for MS downloads
    • Archive restore workflows should use XML template recipes for VLA and ALMA delivery
      • templates provided in CASA 5.6.1/2
      • enable intent selection, target selection, frequency averaging, and time averaging
    • batch request capability
      • upload formatted catalog, obtain cutouts against selected image collections (e.g., ALMA, VLASS)
  • Metadata Improvement: Improved meta-data for products in the archive.
  • CARTA- Archive Integration: Integration of the CARTA viewer with the Archive.
  • Catalog Support: Support for searchable scientific catalogs in the Archive
  • Image Ingestion: If not already complete the ingestion and service of VLASS and ALMA images.
  • Large Project Support: Support for the ingest and serving of products from Large projects as collections.
  • Observatory Calibrator Database: Development of a centralized calibrator database for the VLA.
  • Performance Improvement: Efforts to make the system more responsive and decrease product latency.
