[daip] PBCOR question

[Andrew Baker]

Dear AIPS Team,

I'm running the 31DEC03 version of AIPS that is installed locally, and am 
having some trouble with the PBCOR task.  Specifically, I'm getting output 
images that are identical to input images in all details.  My original 
attempt was to use PBPARM 0.1,1,0.2037,0.20747,0.14087,0.00071739 on an 
OVRO map that was created with IMAGR on another (31DEC99) installation and 
had FREQ in Hz added manually with PUTHE.  I also get input = output if I 
use PBPARM 0.9,1,100,100,100,100-- no blanking at all!-- which seems 
absurd if I have understood the documentation correctly.

Any suggestions for what I should do differently?

Thanks,

Andrew

P.S. - If Eric is fielding this one, congratulations on the Van Biesbroeck
