22:00-03:00; Ioannis, Frédéric: [IM: We start at 22:00, after maintenance and the technical time slot T06-21 that was dedicated to measurements for the telescope efficiencies. Initial NIKA2 tuning looks fine with 29/7/50 bad KIDs for A1/A2/A3, respectively. However, initial pointing and focus yields a strange effect only for 1mm data: 4 images of the pointing source in a cross-like pattern. This was not visible for 2mm data. We repeat the pointing to another source and get the same effect. Then we try to re-start everything: put mirrors back to EMIR setup and then back to NIKA2 setup and restart DAQ and retune KIDs. After these steps the pattern at 1mm data goes away. We have good beam size and shape (~17.7" @ 2mm and ~12" @ 1mm) as well as atmospheric fluctuations are very low (~0.5 Jy/beam). After a calib_1scan [20220301s246] and a beam map [20220301s247] on the quasar 0316+413, we start with observations for the IMEGIN LP (160-16).]
Here is an example with the strange effect at 1mm data. Both plots correspond to the same scan (20220301s241), one for Ar1 and the other for Ar2:

03:00-05:00; Miren: Took over at 2h UT with tau255 ~ 0.125. Starting with pointing. Less than +/- 1 Jy/beam fluctuations and 17.4’’ FWHM beam @2mm. Project 199-16: one repetition on PSZ2G081 (40.5/44) and a repetition on PSZ2G046 (17.5/20). Pointing and focus, followed by a skydip (20220302s32). Sky fluctuations +/- 5 Jy/beam @ 2mm and tau225 ~ 0.15, 17.75’’ FWHM beam @2mm. Another repetition on PSZ2G046 (18.5/20). Ioannis takes over at 4h15 UT.
