shaye

* Made it throug box1, and partial box 2  
* Continuum rms of box 1 ~ 13 mJy. Bit high, but likely due to bad tau. 
* Had to use uvbflag to recover partially shadowed data on C14. 
   Should we uvbflag unflag all shadowed data, and then use csflag to flag shadowed data > X% (e.g. 10%) with the cfaction option? 
* Used 1743-038 for bandpass calibration, need to try using noise source for better look at narrow bands

manuel

* I also used uvbflag to unflag calibrators on C10.
* Narrow lines could not be bandpassed with 0102+584 nor 1743-038.
* I calibrate bpass with 0102+584. 
* RMS continuum: 11 mJy/b for both boxes.

adele

* I see similarly missing amplitude data for  C9 (cal only), C10, C13, C14, C15, C21 (cal only).  Are these all shadowed?

select='ant(18)' # no coherence
select='ant(17)' #bad narrow band amps after calibration -- not sure why, but just took it out
(and uvbflagging of partially shadowed data)

manuel

select="ant(4),time(05:58,06:02)" # higher gains
