Matt,
I have receved the fits file of BL137B you sent me and converted it
into AIPS.
As I understand you use the source 1226+023 as the calibrator and
timerange is: 1/08:26:45-1/08:28:30.
Correct?
I ran PCCOR . You can find the PCCOR inputs(+result) I used and PC
table contents at the files:
BL137B.PCCOR.INP+RUN BL137.PCTABLE
The files are under www.aoc.nrao.edu/~lkogan
Some comments:
1. There is no entry at the PC table for antennas: 1, 2,4,6,7,9 at all
for the selected time interval
(see the file BL137.PCTABLE)
2. PCCOR succesfully finished confirming statement 1
3. The PCCOR output can not be used anyway because 6 of 10 antennas are
not corrected.
4. I do not know why the PC table is so bad
5. Try to reproduce my test result and then we'll move later.

The PC table contents is not good
