VLASS 2022 Priorities

  • Cube Imaging pipeline PIPEREQ-142



VLA 2022 Priorities

Bugs

  • PIPE-1287 - fluxboot failing with target intent using pointing and a CG intent with the pointing setup
  • PIPE-1335 - selection heuristics when delay calibrator mixed with CG intent

Primary Development Priorities

Calibration and Flagging

  • Enhanced DTS issue identification and flagging (CASR-563/PIPE-986)

    • Option to disable bad deformatter flagging completely or partially, PIPE-1183

  • Possible RFI flagging refinements

    • per baseline flagging - PIPE-1286
    • combine targetflag heuristics into checkflag
    • flux calibrator RFI flagging should use residuals - PIPE-1274
  • Change hifv_targetflag to flag target data using a .flagtargetstemplate.txt - PIPE-37
  • Add plots to PI pipeline statwt weblog
    • Only show post statwt plots
    • show box plots for weights per spw, per antenna, and per scan
      • ID places where statwt goes sideways
  • Long solution interval calculation improvement (PIPE-1002/PIPEREQ-64)
  • Short Solution interval calculation improvments (PIPE-1340)
  • Short solint calculation improvement

  • Per-baseband delay solutions (PIPE-670)

  • Spectral window mapping for gain calibration (PIPE-671)

    • enables phase calibration if not enough S/N due to faint calibrator

  • Antenna position corrections in a post-observation time window (CASR-556)

  • Gain table flagging extensions

    • Ripple detection (bad switch problem) (PIPEREQ-11)

    • Gain outlier detection (PIPEREQ-10)

  • Fluxboot gain solution flagging (PIPEREQ-9)

  • Fluxboot QA metric adjustments (PIPEREQ-8)

  • Enable data weights to be determined from switched power (CASR-476)

  • Use MS tool hanning smoothing to enable per spw hanning smoothing (CASR-523; PIPE-672)

  • Spectral window mapping for gain calibration (PIPE-671)

    • enables phase calibration if not enough S/N on narrow spws

  • RFI flagging on uv-grid (CASR-496)

    • avoids flagging of bright spectral lines

  • Cont.dat interpretation to treat non-specified spws as continuum-only

  • Design and set up independent spectral line calibration recipe that could be used by end users or triggered using recalibration workflow


Imaging

  • Detect mosaicked fields and perform joint deconvolution with mosaic gridder

  • Enable basic cube imaging

Stretch Priorities

  • Generalize hifv_circfeedpolcal for all bands

  • Enable experimental P-band calibration

  • Enable pipeline to use two MS files to perform continuum on one and spectral line optimized calibration on the other when spectral lines are a science goal set in PST

  • Define requirements for the continuum imaging pipeline to use outlier fields to remove effects of bright sources rather than using large images
