[daip] CLCAL's opcode 'CALP'

[Amy Mioduszewski]

Teddy,

I think Jim is right that ANTE=0 should be used.  But when you run
FRING/KRING on Y1, here are some tips...

When you run FRING or KRING be sure:
       - the REFANT is the same as in CLCAL
       - GAINUSE is equal to the CL table that is produced
          by running CLCALon the PCCOR output, and DOCAL=2
       - in FRING: DPARM(8)=1
         in KRING: OPCODE='ZRAT'
       - ANTENNAS = Y1 + REFANT

When you run CLCAL be sure:
       - ANTENNAS = Y1, do NOT put the REFANT in this list
       - REFANT is the same as before
       - GAINVER is the same as you used in CLCAL before
         i.e. the CL table with all the calibration EXCEPT
         the instrumental phase corrections.
       - GAINUSE is the CL table ourput bu the last CLCAL i.e.
         the GAINUSE used in KRING/FRING.
       - OPCODE = 'CALI'

If you have a recent enough version of AIPS to have the VLBAUTIL
procedures, there is one called VLBAPCOR which will do all this
for you.

Cheers,

Amy
