Checklist for SRDP calibrations of VLA data, based heavily on the VLASS one.
...
Checklist (in order of pipeline stage):
- hifv_flagdata - online flags. Notify scientist if >20% flagged - maybe should be 35%?
- hifv_priorcals - check for gain compression due to severe RFI - is hifv_syspower part of the regular pipeline yet? If not, probably need to flag.
- hifv_testBDdcals - check for Data Transmission System (DTS) problems.
- hifv_flagbaddef - check that any DTS issues have been flagged.
- hifv_semiFinalBPdcals - check for any remaining DTS issues.
- hifv_solint - check solints for calibrators are reasonable (< a few mins for the long interval, > ~0.1s for the short interval) - if in doubt check with a scientist.
- hifv_fluxboot2:
- check the input tables look clean
- check that the model is reasonable and covers all spw.
- make a note of the phase calibrator flux densities.
- hifv_finalcals:
- check for delay outliers
- check for unusual bandpass shapes
- check for outlying bandpass phases
- phase (short) gain solution: check for large phase scatter
- final amp/time: check for outliers
- final amp/freq: check that outliers fall into known bad spw
- Final phase - check there are no phase jumps > 90deg
- hifv_applycals: check end of CASA log and note final % flagged. If over 50%? check with a scientist
- hifv_plotsummary:
- phase vs time plots: check all are centered on zero
- amp vs uvwave:
- check calibrators are point-like (constant flux)
- check there is no evidence of decorrelation (strong "waterfall")
- check RFI is fully flagged
- amp vs frequency:
- check for residual RFI on calibrators
- check for residual RFI on targets
- Rerun with additional flagging if needed.
- Once satisfied, write a short overall evaluation suitable for transmission to the PI (no cuss words!)
