                                [2012-08-25 21:21]TP : Subtracted time when source was below
                               30 degrees elevation.

* C8 out
* C23 no coherence
* 1743-038 observing at low elevation (28, 23, 18 degrees) in last hour. Some 6-m gains go way up. 
   Obs said they did this to fill a gap and won't charge that hour. 
* The partially observed top box looks funny. It has the full N-S extent, but not the full E-W extent. How is it being mapped???
   It was a problem in the OTF mosaic parameters. Fixed it.

* C17 had high Tsys when observing 3c279 but the data still can be used with bpass calibration purposes 
  (at least it works for the wide band, not seem so for narrow bands, where solving for bpass with C17 creates some problems).
* C7 had a phase jump between t(05:42:42,06:43:43)
* rms cont: 12/10 mJy/b
* rms window 4: ~0.83 Jy/b . km/s
* SDish: (average signal-to-noise-ratio taking into account the maps from all antennas and possible bad antennas)
   -window1:                <snr> ~ 5.1 === c5 had snr=2.8
