Hello,
TDEM0023 was executed on Feb 10. I would like to use both AIPS and CASA to work on these data. In attempting to get the data into AIPS format, I have run into an issue that I hope you can help with. I use BDFLIST and BDF2AIPS on machines in Socorro for this process. I follow the same procedure here as I did for data from TDEM0021 (acquired Feb 2016), and I successfully imported those data into AIPS.
Specifically, BDFLIST returns two configurations for the dataset. There is one and only one IF setup. I can run BDF2AIPS twice to write out two UVDATA files. Upon copying those to my local machine, I cannot use UVLOD to get them to create one single UV database. I could use DBCON, but I hope that there is something simple that I am missing? I believe that only one database should be able to hold all of the data.
My specific steps are as follows:
***** SSH to thuban in Socorro and use local AIPS for BDFLIST and BDF2AIPS:
1. Archive query, use SDM format and create tar file.
2. ssh nm-609 at ssh.aoc.nrao.edu
ssh thuban
export VLADATA='/home/thuban/cannon/'
3. Get the tar file to thuban:
wget https://archive.nrao.edu/secured/LOCATION/name.tar --user=name --password=password
4. Un-tar file in /home/thuban/cannon/
5. BDFLIST:
task 'bdflist'; default;
dowait 2; docrt 1;
asdmfile(1)='/home/thuban/cannon/TDEM0023.
asdmfile(2)='sb33475582.eb33486694.57794.55308493055
bdflist
--> 2 configurations, numbered [0] and [1]
6. BDF2AIPS:
task 'bdf2aips'; dowait 2; docrt 1;
asdmfile(1)'/home/thuban/cannon/TDEM0023.
asdmfile(2)='sb33475582.eb33486694.57794.55308493055
outname 'UGC11411
outclass 'uvdata'
bdf2aips
--> Have to execute TWICE, since there are 2 configuration #s
output by BDFLIST. I am not clear why this is so.
task 'bdf2aips'; dowait 2; docrt 1;
asdmfile(1)'/home/thuban/cannon/TDEM0023.
asdmfile(2)='sb33475582.eb33486694.57794.55308493055
outname 'UGC11411
outclass 'uvdata'
config 1
bdf2aips
7. Write out UV databases:
run wrtprocs
task 'fitdisk'; default;
getn 1;
dataout 'VLADATA:
fitdisk
--> File UGC11411.UVDATA.1 written
task 'fitdisk'; default;
getn 2;
dataout 'VLADATA:
fitdisk
--> File UGC11411.UVDATA.2 written
--> Copy to my local machine via scp:
scp nm-609 at ssh.aoc.nrao.edu:/home/thuban/cannon/UGC11411.UVDATA.1 UGC11411_1
scp nm-609 at ssh.aoc.nrao.edu:/home/thuban/cannon/UGC11411.UVDATA.2 UGC11411_2
Now on my local machine, load into AIPS:
task 'uvlod'; default
datain 'vladata:UGC11411_'
outname 'UGC11411'; outclass 'uvdata';
doconcat 1; outseq 2;
go
Only 1 database is read in by UVLOD. The AIPS header verifies that the frequency setups are the same:
