FILLM has had a bug described below from Sept 13 until tomorrow morning.
It affects primarily CL table gains for high frequencies when the
program changed bands during the observations.
12737. October 20, 2008 FILLM Eric
The change of September 12 (#12709) had unintended
consequences. The band changed to the new band before the
present scan was finished. The only known consequence was to
the last record in the CL and TY tables. The latter would
matter only for 4 or P band and would cause a different system
temperature to be chosen. The CL table however would have the
atmospheric opacity and antenna gain correction for the next
band rather than the present band. This could make a
substantial (e.g. 5 %) difference in the gains. Use of INDXR
to make a new CL table erases this problem.
Changed the code to find the new band only for deciding about
keeping the data or not but leaving the band ID unchanged
until the data are fully absorbed.
Moved nowhere.
Sorry about that..
