[daip] Project BS077 (Sept.30,1999)

[Leonia Kogan]

Peter,

Your input parameters look fine for me.
 
Check that all antennas were involved at the observation at the TIMERANG of 
PCCOR. Use POSSM with DOCALIB = -1 to see if the phases are smooth 
(for separate IFs) at the nine baselines (all antennas with REFANT=5) for the selected TIMERANG (selected at PCCOR).

Repeat POSSM with  DOCALIB=1 and GAINUSE=2 for the same TIMERANG.
THe phases have to be allign for all IFs and all 9 baselines.

I hope that GAINVER=1 (used by you at CLCAL) corresponds to the virgin CL table with REAL=1, IMAG=0 for all entries. Does it?

Please check the SN table 1 (the output of PCCOR) using PRTAB or SNPLT.
All amplitudes should be equled to one. All antennas have to have entries.

Send me the output of LISTR of the data with OPTIPE='scan"

Do you have one FREQID at your data?

Leonia

Leonia,

Yes our project was a VLBA one done on sept30, 1999.  I've looked at the pcal 
plots and the phase vs time are smooth and fairly level for each antenna so 
PCCOR should have worked.  Here are my inputs for Xband:

Here are the inputs for PCCOR:

AIPS 1: INNAME 'bs77-x' 
AIPS 1: INCLASS 'uvcop' 
AIPS 1: INSEQ 1 
AIPS 1: INDISK 3 
AIPS 1: TIMERANG 0 20 56 0 0 20 58 0 
AIPS 1: SNVER 1 
AIPS 1: INVER 0 
AIPS 1: REFANT 5 
AIPS 1: SUBARRAY 0 
AIPS 1: FREQID -1 
AIPS 1: CALSOUR '1611+343' 
AIPS 1: CUTOFF 0 
AIPS 1: BIF 0 
AIPS 1: EIF 0 
AIPS 1: DELCORR 1


And for CLCAL:

Thanks for the quick reply.  Just to let you know, Amy Mioduszewski replied as 
well.
