Dear Reader,
I'm using the 31DEC04 AIPS version to reduce WSRT LFFE 330MHz data.
The MS consists of first calibrator, the target, and a second
calibrator.
After SPFLG which ended normally (although I flag quite some bits) BPASS
won't find any solutions.
I ran SPFLG for different stokes and w/ docal 1.
BPASS as in the attached files (w/ flagver -1 it no bad results).
It makes no difference if docal is 1 or -1. IF 8 is totally flagged, but
using eif 7 and several ichans did not work out.
Do you know what is going on? It would be very helpfull.
Thanks so far.
