                                [2012-07-13 10:34]AS & LR : Data look good overall. Track
                               was run for 5.8 hours in total, but we did not subtract the
                               last hour to the project because of very high opacity.

* John C took an independent look at this dataset on request of Lee
* He recommends it gets redone
* Lee will pass that info to NV once he is back from vacation 

* Based on manuel's flags, I get 13 mJy rms for continuum in all boxes
* so if that is 2x worse than usual, getting charged for 1/4 time is fair (?)


manuel

*Bad weather track (tau~2 with peaks up to 10, rmspath:200-500)
*2 peaks on tsys at ~6.20 and ~9.00 LST
*C16 and C19 again have higher gains than the other antennas.
*C9,C21 have not good data for Neptune (shadowed??)
*Several antennas shadowed mainly while observing 1743-038 at the end of the track
*The Tsys of this track is ~200 K above that of the others
*I detected 2 of the main 3 continuum sources up to a 3-sigma threshold (~36 mJy/beam)
