[daip] visibility order problem

[Tracy Clarke (Foreign National)]

Hi Eric,

 	I'm working with a data file that I have run a couple of phase 
self-cal's on and run into a problem while trying to flag some data. When 
I try SPFLG or TVFLG I get the following error messages:

CAIRO > TVFLG1: Begin finding a list of times to enter the grid
CAIRO > TVFLG1: TIMES OUT OF ORDER:  1.452020E-01 <  1.452020E-01
CAIRO > TVFLG1: AT VIS #           2 APPARENT ROW     0 <     1
CAIRO > TVFLG1: Purports to die of UNNATURAL causes

I can flag the original data set but this error starts as soon as the 
first phase self-cal and persists after that. I can run IMAGR and UVPLT 
but I really need to flag it. Is there anything I can do to fix this? I 
tried a UVSRT going to XY then a second back to TB but get the same error 
message. Looking at the history file the only thing I ran between the file 
that works and the first one that doesn't is a CALIB. Thanks for any 
ideas. Cheers,
 							Tracy
