[daip] Load multiple fits files with FITLD

[Arnaud Collioud]

Hi Eric, Hi Amy,

I am trying to process an EVLA dataset (project 12B-108) with AIPS (31DEC12).  Once downloaded on NRAO archive, I got 2 uvfits files per observation (total of 4 files). I am trying to load the 2 uvfits files in the same AIPS file (as I am supposing that the 2 uvfits are 2 parts of the same observation) with FITLD, but without success. FITLD always creates 2 separate AIPS files. 
Am I doing something wrong ?

Thanks !
Best regards,
Arnaud
