                                [2013-02-11 19:51]A Schruba : Good weather. Bad antennas
                               are: C5 intermittend bad locking, C2, C9, C15 C18, C19, C22
                               bad pointing; C14 out of array. 50% time charged.

manuel

* Decent weather track. C14 out of the array.
* Applied new baseline solutions (antpos.130210). 
* C2, C18, C19 & C22 are uncorrelated. C19 shows steep slope in phase when plotting baseline spectra.
* C4 shows bad amplitudes at the beggining of the track possibly due to bad pointing?
* C8 & C19 show ripples in amplitude. 
* C15 did not observe 3C279 (even after uvbflag).
* C16 shows higher gains at around ~1.2.
* The overlapping region between the 2 boxes was no mapped.

* cont RMS box1/2: 10/11 mJy/b
* HCO+ cont bo1/2: 0.95/1.10 Jy/b
* WB: different gains (and high) than for the SL track ??? --> data may not be useable

shaye

* I don't see why C2 needs to be tossed for the whole track
   Seems like the pointing was nailed down after ~1 hr into the track
* Don't see problems with C5, C9, C15 that obs notes
* BP with noise
* Flux of 1743-038 ~3.9 Jy
* cont RMS box1/2: 10/13 mJy/b
* HCO+ single channel rms box1/2: 0.8/1.0 Jy/b
