Hi Lincoln,
Thank you for your quick repeat message about possible BUG at ACCOR related
with negative SOLINT.
I will change the default of SOLINT having discussed it with other people
of AIPS group.

Hi Leonia,
Sorry that my gripe was written too quickly and before I inspected ACCOR
code.
I suggest that the program permit negative solints but not enforce scan
averaging when this is done.
It will be necessary to address the meaning of solint=-1. Perhaps scan
averaging can be commanded instead with solint=0. What do you think?
solint (cf CALIB).
I very much appreciate your and Jim's careful replies to my questions re
rapidly varying structure in the ACCOR solutions. Though I see complex
patterns, I believe there is intermittent structure consistent with Jim's
suggestion that I would see a sawtooth pattern. Since I am observing at 7
mm, atmospheric variability will be superposed on the sawtooth, so it is
only sometimes visible.
Since some deliberation will be necessary on your part to figure out
whether/what changes to make to ACCOR, I will make changes to our local
ACCOR to suit my processing for the moment.
Regards,
Lincoln
