[daip] a problem with ANCAL/ANTAB (fwd)

[Amy Mioduszewski]

Hi Victor,

The calibration info will be in the TY and GC tables.  You
can look at the TY table in SNPLT and unfortunately the GC
table only with PRTAB.  If there is a problem with FITLD
that it does not get the TY and GC tables right because of
the splitting into different sources/freqs that is a FITLD
bug.  So I would strongly encourage you to check out the TY
and GC tables.  Also since they already exist if you run ANTAB
with TY=0 and GC=0, ANTAB will create new TY and GC tables.

Hi Amy, 


	We observed over 50 OH maser sources which means the same 
	number of different sky-freqs.  When FITLD starts reading 
	the correlator tapes it goes a bit crazy because there is 
	a limit for the FREQID parameter .....hence it 
	creates many files with a different number of sources. In 
	away, this is not bad because it is easier to deal with a 
	few sources per file than having to keep track of many BPs, 
	SNs and CL tables in a much larger file. Because of this I 
	am not sure all the appropriate info is where it supposed to 
	be. So the TSYS info is in the original CL table? Or in the 
	TY table?  I have never used these option since it has been 
	available ...... Also, being spectral line data I like to use 
	the auto-correlated spectrum to do the amplitude calibration, 
	but I still like to check this calibration with the one done 
	with the TSYS information. I'll try using VLOG ......
	
	
	cheers,
	
	
	
	Vic.
