[daip] UNKNOWN POL message

[Brian Kent]

Hi Eric,

Yes, I just checked - if I type print DOPOL, I receive:

AIPS 1:      1

So DOPOL is set to TRUE.  I just reset it to FALSE, and I don't get the
message (I'll go back through my steps now so I can recreate everything
this afternoon).

In section 4.9.2 it says to set DOPOL to TRUE, so I guess that's why I had 
it set to that.  But yes, since I can't calibrate the pols, then I should 
have it set to FALSE.

Thanks again for your help - on to the next step!

-Brian
