Demerese (final)

  • uvflag vis=$vis edge=2 flagval=flag
  • uvflag vis=$vis tsys=400. flagval=flag
  • uvflag vis=$vis select="ant(1,3),win(3)" flagval=flag #tsys
  • uvflag vis=$vis select="ant(8),time(23:50,0:10)" flagval=flag #bad/cal
  • uvflag vis=$vis select="ant(13)(14)" flagval=flag #phases/cal
  • uvflag vis=$vis select="ant(23)" flagval=flag #gains/phases

Demerese's notes: Flags with #tsys label are actually unnecessary commands due to the second flag listed above. The #auto labels are also unnecessary as they just highlight automatically flagged data.

Shaye (final)

  • uvflag vis=$vis edge=2 flagval=flag
  • uvflag vis=$vis tsys=350. flagval=flag
  • uvflag vis=$vis select="ant(1,3),win(3)" flagval=flag
  • uvflag vis=$vis select="ant(23),time(00:15:00.0,03:45:00.0)" flagval=flag
  • uvflag vis=$vis select="source("$cal"),time(00:00:00.0,00:05:00.0)" flagval=flag

Main Demerese/Shaye Differences

  • Both have: uvflag vis=$vis select="ant(23)" vs. uvflag vis=$vis select="ant(23),time(00:15:00.0,03:45:00.0)"

Shaye's note: Ant 23 has reasonable gains for part of the trial

Demerese's response: I agree that the calibrated data outside the time range (0:00,3:45) looks okay...

  • Shaye has: uvflag vis=$vis select="source("$cal"),time(00:00:00.0,00:05:00.0)" flagval=flag

Shaye's note: Calibrator phase a bit messy for a couple of minutes

Demerese's response: Does flagging ant(8) for this time period fix this?

  • Demerese has: uvflag vis=$vis select="ant(13)(14)" flagval=flag #phases/cal

Shaye's note: I agree the amplitudes are scattered compared to the rest of the baselines, but wasn't enough for me to flag

Demerese's response: The scatter for baseline (13)(14) in my data is about 7Jy vs 1Jy for the other baselines (in the calibrated amp vs time plot after selfcal)

  • Demerese has: uvflag vis=$vis select="ant(8),time(23:50,0:10)" flagval=flag #bad/cal

Shaye's note: I don't see this.

Demerese's response: In this time range, ant(8) gives higher amplitudes (about 13Jy) on all baselines vs 11.5Jy for the rest of the trial. Use smauvplt vis=$vis.cal axis=time,amp device=/xs select="source("$cal"),ant(8)".
