Hi NRAO helpdesk,
I am contacting you in reference to project code BA196B. I am in the process of reducing the dataset and would appreciate your help with a step I am stuck at.
The data contains the usual VLBA array and Y27. This is the first time I am reducing such an array and am unable to get my antab file for the Tsys of Y27 to load up properly in AIPS. I am describing the steps I am following below:
I first downloaded the file 'BA196A.0.cal.y' from the link below http://www.vlba.nrao.edu/astro/VOBS/astronomy/sep25/ba196b/ . I have also attached the file I end up downloading as 'antab.txt'.
Next I ran the following commands for the task ANTAB.
default antab
getn 25
calin 'PWD:antab.txt
tyver 1; gcver 1
go
I can see the GC table getting updated but some reason the TY table isn't. I get the following message once the task ANTAB is done running:
LOCALH> ANTAB1: 0 TSYS records read for station: Y
LOCALH> ANTAB1: ! ----- Gain information for Y -----
LOCALH> ANTAB1: !
LOCALH> ANTAB1: Y GAIN ALTAZ DPFU= 2.8000 , 2.8000
LOCALH> ANTAB1: POLY = 1.0 /
LOCALH> ANTAB1: Gain curve read for station: Y
LOCALH> ANTAB1: ! BAND = 'X'
Do you have any suggestions on how I can solve this such that both the TY and GC tables get updated with information needed for amplitude calibration of Y27.
Cheers,
Pikky
