Yes, Amy, I think you're right.  Our multi-band solution on the manual phase
cal scan (not the one you have) *does* look OK.  Somehow the one good one got
lost amongst all the bad ones.

We ran TST for the multi-band solution because NEW was unable to handle our 
setup of unevenly spaced/overlapping bands.  NEW gives huge phase jumps 
(of order 180 degrees) between bands.


Thanks for your help,
