Hello,<br>My name is Rita and I am currently mapping some sources from the VLA-Archive.<br>I used to run AIPS on Jodrell Bank's machines and now I've installed AIPS on my laptop. Instalation was smooth.<br>I've used an amplitude and phase calibration on my data retrieved from the Archive and now, when I use IMAGR to map the source I get these errors:
