Check the Cryo run 87 (run #75 of NIKA2) is activated in DAQ *.ini files, as well as for the creation of imbFITS files (new & old systems).

Data obtained in the previous run (#74) were reprocessed using the PIIC/DAFs in force.
A note about focus corrections: data of run #74 was reprocessed with the Best focus offset of Ar1 wrt. Ar2 is ~ +0.5 mm, and ~ +0.2 mm for Ar1 wrt. Ar3 (see plot below; linear fits are weighted by inverse rms values).
First of all, check the focus offsets in total power after the cooldown. Over run #72 focus corrections of Ar2/1 were self-consistent and that of Ar3 was +0.3-0.4 mm displaced. On run #73, we obtained offsets of about +0.3 mm for Ar2/1 and +0.6 mm for Ar2/3. Depending on these tests, we would establish appropriate compromise values.
Beam maps to produce new DAFs/kidpars with new reference KID (Ar2, central KID).
Calib_1scan maps on flux standards in total power & polarimetry. In the latter case, get focus correction from Ar1-Ar3 average.
Small maps on point-like & extended (auxiliary) bright sources.
