Hi Eric,
Has something significant changed in '07 CALIB?
I have been trying to self-cal a 74 MHz dataset using AIPS07. I finally
tried '06 because the very poor results I was getting in '07 (almost no
good solutions) was quite inexplicable given the quality of the
data/model. On the face of it I would suggest that there is either a VERY
significant bug somewhere or the parameter meanings have changed
drastically. Maybe it could even be a problem with C'ville install.
Using identical parameters, I get the following results:
