Daily Reports (2025/10/21-28, NIKA2 run 75, Cryo run 87)
Observers on-site: Monica Rodriguez, Samuel Leclercq, Raphaël Maris, Stefano Berta and Stergios Amarantidis (AoD).
Remote observers: Michael Mattern (Saturday-Tuesday).
Operators: Sergio and Mario.
Shifts: 10-16 Raphaël; 16-22 Samuel; 22-4 Stefano; 4-10 Monica.
All times reported are in UTC (if not mentioned otherwise).
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 use the custom modified focus script focusOTF-Z_2025.pako.
Therefore, importantly, when checking the quality of the beam on a pointing map to decide if a new focus is needed, it is better to do it on the Ar1 map, because that's the one focused at best.
Project D01-25 (M51) requires DAQ restarting with the run87_newSweep_M51_tp.ini file. Come back to run87_neSweep_tp.ini after observing this project.
Please fill the Table with the Ar1,2,3 focus values as follows. At best, make one table per day.

15:00-22:00[All]: Maintenance finished with no issues. DAQ started at 14:10 with 21/3/47 bad KIDS for arrays 1,2 and 3, respectively. Repeating the DAQ at 14:24 with 28/3/89. Trying to point at NGC7027 and MWC349 but the weather is too unstable (p2p~10-20Jy/beam), moving to K3-50A for pointing and focus (using the modified 2025 script). Moving for calib_1scan to MWC349, etc. Switching to project 053-25 (source 1803+784 is better for pointing/focus). One repetition of L1157B. Around 17:12 we moved to a skydip and then to the normal flux calibrators. After pointing/focus on 1803+784 we move to project 022-25. Two repetitions of Ceph-4.
22:00-04:00[Stefano]: here follows the evolution of the night:
- I let the 022-25 observations finish
- some difficulties in focusing properly, due to sky fluctuations combined with the big difference between Ar2 and Ar1
- 053-25 one repetition on L1157B (4 scans)
- calibrations (MWC349, CRL2688, NGC7027)
- 053-25 one more repetition on L1157B (4 scans)
- calibrations (Neptune, Uranus)
I decide not to take any beam maps on Uranus, because: a) the sky is not stable enough; b) in principle we'd need three beam maps, focused on each of the three NIKA2 arrays independently!
