[daip] Self-calibration problems

[Carlos Vargas]

	To who it may concern:

	My name is Carlos A. Vargas Alvarez, a student working at the Arecibo
Observatory/NAIC, and AIPS user.  Currently I'm using 15APR98 version, and I'm
trying to self-calibrate Q-band data from the VLA.  I'm having a lot of troubles
trying to figure out what to do, and the AIPS Cookbook and the book Synthesis
Imaging in Radio Astronomy II are not helping a lot.
	Finally with CALIB I got the next solutions:
		282 good solutions
		110 failed solutions
and		81 with insufficent data
When I then rum CLCLA to end the self-calibration and then IMAGR to see what 
is new, I got an imagr in where the source that I used has a model disapered and
the r.m.s noise have raised by a factor of 2.  I have tried to run diffents 
interpolations and smoothing on the data but I still don't get the results I 
want
	So I'm asking you to see if you any idea of how I can attack this 
problem and finally self-calibrate data.
