Dear All,
I loaded my data wit 'ATLOD' and aparm(1)=-1, aparm(3)=1, aparm(7)=1, the
rest set to default. The visibilities are incorrect. The visibilities are
for the first scan and this has become a problem when I run 'CVEL'. 'CVEL'
only do run for the first scan. My 'imh' and 'LISTR' are as follows:
AIPS 1: Image=0637-752 (UV) Filename=0637-752 .UVDATA. 1

'CVEL' on
it. It works but when I plot the visibilities I get the following errors:
