Serpens Main Trial 4D Flags

Notes

  • Really good weather. Some antennas have gains below 1.
  • C23 lack coherence the entire time? (looks like it on real-time gains page)
  • C7 out of array
  • C20 & C21 have some auto flagged on the middle of the track
  • C18 bad during 3c279 observation --- need to solve for bandpass solution differently from the other antennas
  • Extra passband calibrator (3c453.3) observed at end by observer choice, probably due to C18 problem.

Shaye

  • I screwed up the expansion of the middle and right rectangle, causing them to misaligned with the left rectangle. Not a huge deal, but the pointings will all be off by a small amount from the rest of the trials. This was caught before trial 6 and will affect trials 4 and 5.

                                [2012-05-11 07:13]SM : C7 out of array. C23 shows very high
                               gains. C18 & C22 shouw tsys jumps at the end of tracks. Great
                               weather.

Flags

Shaye

 select="ant(23)" #no coherence
 select="ant(18),source(3c279)" #very him amp
 select="ant(22),time(13:00:00,13:15:00)" #tsys spike
 #auto flagged data for C20 and C21 for large chunk of track???? tsys looks fine .. not sure why

Manuel

 Exactly the same flags that Shaye
 refant=8
 edges=2
 select="ant(7)" #no data
 select="ant(23)" #no coherence
 select="ant(18),source(3c279)" # high tsys & amplitude
 select="ant(22),time(13:04:00,13:13:10)" #tsys

Adele

 Agreed
 Also: 
 select="ant(20),time(10:48,13:14)" #no 1743-038
 select="ant(21),time(10:00,12:13)" #no 1743-038
