| 15:30-18:00 Ioannis : Maintenance finished on time and start directly with NIKA2 observations. ~ 1hr of NIKA2 observations training with new observers (and the ones that want to refresh their memory). Started with NIKA2 total power to check stability. Tuning looks good (12/5/21 bad kids for Ar1/2/3) and pointing plus focus look consistent and stable. Sky looks stable (~ 1.5 - 2 Jy/beam at 2mm) and we decide to change to NIKA2-Pol. | 15:30-18:00 Ioannis : Maintenance finished on time and start directly with NIKA2 observations. ~ 1hr of NIKA2 observations training with new observers (and the ones that want to refresh their memory).

Preparatory notes
Please, remember to use the focus value of Ar1 (roughly Ar2 + 0.65 mm, but use directly the focus Ar1 monitor if possible).
Please fill the Table with the Ar1,2,3 focus values as follows. At best, make one table per day.
