Important
Focus offsets shall be measured on Ar1
Pointing offsets shall be measured on Ar2
Pool-Account usage: Accounting of observing times
Calibration observations like pointing, focus, and calib_1scan (the latter in case of NIKA2-Pol only, aimed at characterizing the instrumental polarization) which are conducted before and during project observations are part of the project time. Note that all proposals include such overheads in the time and sensitivity estimates. This holds for total power and polarimetry observations.
Other calibration observations which are important for all projects like beam maps, skydips, or calib_1scan for absolute flux calibration may be accounted under the pool account (nikaX-YY, where X = s,w and YY = year ; nikaw-25 in this case).
- When conditions are unstable and it is unclear whether project observations make sense at all, calibrations may be accounted to the pool account.
Focus and Beam maps accounting
Please fill the Table with the Ar1,2,3 focus values as follows. At best, make one table per day.

- parked because of wind
- @22:00 UT we start with NIKA2-Pol. Lost KIDs 14/5/25; spiky taumeter; flying clouds; tau(225)=0.2-0.3.
- after the startup with point/focus/point, we move to 084, calib_1scan on Uranus and pointing on a nearby source. The sky is too variable. We stop for 30 minutes to see if the conditions improve.
