Dear VLBI experts in AIPS helpdesk:
My name is Chengyu Kuo, a UV graduate student. I have a question
about AIPS again!
Part of my VLBA observation is to observe many geodetic calibrators to
determine the zenith
atmosphere delays and clock errors. For one of my geodetic datasets, I have
problems to
do VGBLU properly.
The program ID for this dataset is BB242H. There are two freqids
for the geodetic observation,
and I need to VBGLU the two freqids to stick all 8 IF bands together.
However, for some unknown
reasons, VBGLU cannot stick them properly. The AIPS message is attached at
the end of this email.
I also attach the jpec image of what I see by using EDITA to view the TY
table with this email. There are many data that have zero system
temperature. However, if I do this for each freqid separately, there is no
such a problem.
In addition, this problem seem to affect the calibration process. I
cannot do instrumental
delay calibration properly. There are big phase offsets between the two
freqids for GBT for the geodetic blocks affected by the mis-match after
VBGLU. I did not see this problem in my other datasets. Could you help me to
take a look of this problem. Thank you for your time!
regards
chengyu
