| * AB: Considering the circumstances in which this campaign will be carried out (heterodyne pool), the most practical approach would be to obtain (i) a pair of beam maps per array with optimized Z foci (first priority), and (ii) obtaining the deep fields (~5h in total) in one of the sources to be selected (use @generic_otf_radec). | * AB: Considering the circumstances in which this campaign will be carried out (heterodyne pool), a practical approach would be to obtain (i) a pair of beam maps (@ 202503/beammap1scan99sub a; 25 min) per array with optimized Z foci (first priority), and (ii) obtaining the deep fields (~5h in total) in one of the sources to be selected (use @ 202503/generic_otf_radec; 12.4 min). If there is more time, continue with the defocused beam maps (Delta_Z = 0.2 mm). Some @calib_1scan maps (4 min each) on primary/secondary flux calibrators would be desirable. |

Preliminaries
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).
- Check that imbFITS files are being produced by both the new and old systems.
- Data obtained in the previous run (#74) were successfully reprocessed using the PIIC/DAFs in force (/sw/gildas/mopsic/dafs). So, the default PIIC/DAFs mentioned in the document linked below are very likely to work. Best focus offset of Ar1 wrt. Ar2 is ~ +0.5 mm, and ~ +0.2 mm for Ar3 wrt. Ar1 (see plot below; linear fits are weighted by inverse rms values). Check these focus offsets.
Goals of NIKA2 run 75 (Re-commissioning of NIKA2+, fourth part)
