VLASS 2022 Priorities
- Cube Imaging pipeline PIPEREQ-142
- Resolve calibrator handling PIPEREQ-132
- Imaging fails in somecases in 2021.2 (PIPE-1173)
Change VLASS parameter compressionusemedian default from False to True (PIPE-1338)
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
- PIPE-1098 - cont.dat failures for targets with some characters
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 - (PIPE-1342)
- flux calibrator RFI flagging should use residuals - (PIPE-1274)
- Backup flags in hifv_applycal prior to calibration (PIPE-854)
- Change hifv_targetflag to flag target data using a .flagtargetstemplate.txt - (PIPE-37)
- Add plots to PI pipeline statwt weblog (PIPE-1341)
- Long solution interval calculation improvement (PIPE-1002/PIPEREQ-64)
- Short Solution interval calculation improvments (PIPE-1340)
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)
Self-calibration
- Enable self-calibration heuristics for continuum data only in new task (hif_selfcal) and operate on only the _cont.ms (PIPE-)
- Joint ALMA and VLA development and should work on both types of data
Spectral lines
Cont.dat interpretation to treat non-specified spws as continuum-only (PIPE-1043)
Design and set up independent spectral line calibration recipe that could be used by end users or triggered using recalibration workflow
- Save pre-target RFI flagging and split non-RFI flagged data after hifv_statwt using a new task (PIPE-)
- For VLA data, enable steps to run findcont to only run on line spws
- hif_makeimlist(specmode='mfs')
- hif_findcont()
- hif_uvcontfit()
- hif_uvcontsub()
Spectral window mapping for gain calibration (PIPE-671)
enables phase calibration if not enough S/N on narrow spws
- Waiting on CASA development
- RFI flagging on uv-grid (CASR-496)
- avoids flagging of bright spectral lines
- RFI flagging on uv-grid (CASR-496)
Weblog
- Zoom feature for all hif_makeimages plots (PIPE-1083)
- plot labels in semifinalbpdcals (PIPE-984)
- parallactic angle vs time plot (PIPE-836)
- Add API plot to VLA pipeline runs (PIPE-580)
Minor things
- Report total MS sizes at end of calibration on main weblog page (PIPE-1166)
- multi-band weblog plots should not use shared time axis for plots (PIPE-1044)
- Zeros flagged not reported properly (PIPE-1033)
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
