[daip] CLCAL's opcode 'CALP'

Hi,

I am working on a VLBA+Y1 expt and am applying the pulse-cal information
for the VLBA...I will do the manual phase cal for Y1 soon.

I ran PCCOR successfully, giving me SN3. I tried to apply SN3 to my latest
CL table (4) to create CL 5 with CLCAL, opcode 'CALP', antenna -11,0. I
hoped that this would pass antenna 11 (Y1) uncalibrated but I looked at the
new CL table (5) with Possm and there is no data for Y1. What do you think
is going on?

Appended is a copy of the parameters I used.

Thanks,

Teddy
