[daip] polco problem

[Amanda Kepley]

Hi,

I'm trying to use POLCO to correct some polarization maps for bias and 
am getting some weird error messages. I'm taking a legitimate polarized 
intensity map and running POLCO with the following parameters:

AIPS 1: POLCO: Task to correct polarization maps for Ricean bias
AIPS 1: Adverbs     Values                 Comments
AIPS 1: ----------------------------------------------------------------

AIPS 1:                                    else use magic blanking

I've tried this with a couple of difference files on a couple of 
different AIPS disks, but get the same ZOPEN, CATKEY error messages. The 
output image appears to be okay though. It this a problem with my 
installation or with AIPS itself? I'm running the latest MNJ version of 
AIPS.

Cheers,

Amanda
