Stuart,
About the model data:
You wrote:
aips > getn 47
aips > tvlod
Then up pops the image in the tv window
aips> mcat
AIPS 1: 47 2 TEST .IMAG . 2 MA 13-MAY-2006 21:01:47
This mean that the relevant inputs for UVCON should be:
IN2NAME 'TEST' ( you used the same => correct)
IN2CLASS 'IMAG' ( you used '', wrong)
IN2SEQ 2 ( you used 47, wrong)
INDI <the disk number> probably 1
If you type
get2n 47
as I wrote you in the previous message, you'll get the right in2puts, or you have to use the in2puts, picked up from the line:
AIPS 1: 47 2 TEST .IMAG . 2 MA 13-MAY-2006 21:01:47
see above.
This is solution of your problem finding the model.
The INFILE has to be fixed as I explain you at the previous message.
Good luck
LK
