Daily Reports

Because of the pandemic, no observers can come to the telescope. This pool is entirely in remote mode.

Gentle reminder by the PIIC team (edited AB): each time you perform pointing and/or focus on a calibrator, please perform also a calib1scan (~4 min only). Please take the time to do it even if the weather is spectacular and you want to dedicate as much time as possible to science scans. It does not take long and you collect precious information. This is very important to answer some unsolved questions. Primary/secondary (compact) calibrators you can use: Uranus, Mars, Neptune, CRL2688, MWC349, NGC7027, 3C84, 3C345, 3C279. The latter ones are available in the NIKA2R6 catalogue. More calibrators from Planck point-source catalogue will be provided asap.

16h - 21h; Angel, Bilal: Smooth start of the pool, no problem to report, mediocre weather starting but improving a lot during the evening.

21h - 03h; Golshan and Suzanne: We started out a bit blocked when the desktop screens froze and had to be restarted (our restarting VNC did not solve the problem). We could not change desktops as usual and Bilal found a solution. The tau values were always < 0.18 and most of the night~ 0.15. Early on the sky fluctuations were not great (5 to 10 Jy/beam on array2), but improved during the night. We did a beam map on 3C279. We were not able to do a calib scan on CRL618 as it was too low. At the end of the shift we did a skydip We observed 160-16 NGC3627 (IMEGIN) for 4 repetitions (2h) this galaxy is not yet completed - needs 4 more hours to complete. We observed 180-20 project for 2 hours.

03h - 09h; Isabelle and Karine: The observations conditions were excellent : with an opacity of _0.15, very stable, and perfect beams. We first observed for project 181-20 , source RXJ1347 , with 2 Nreps (2h), we then observed for project 107-20 on L1689A with 2 Nreps (~ 2h), then we observed GP_L23p3 from GASTON Galactic plane project, with 2 Nreps (1h).

09h - 15h; Chenlin: The opacity was good (around 0.15). We started the observations for project 122-16 with one repetition of GP_L23p9 and two repetitions of GP_L24p5. Then we observed for project 175-20 with one repetition of NEP_L. From 2pm, the beam size became larger and asymmetric. We did calib_1scan and a skydip. And we kept doing pointing and focus to monitor the beam till the end of the shift.

15h - 21h; Bilal: The sky conditions and beam parameters were bad, but improved a lot by 5pm.

21h - 03h; Golshan and Suzanne: It was a very stable night: The tau values were always < 0.2, hovering around ~0.18 most of the night. The sky fluctuations were quite good and steady all night: ~ +/-5 to 3 Jy/beam on array2. We did a calib1 scan on CRL618. A beam map on 3C279 was started at the end of our shift. We observed 160-16 NGC3627 (IMEGIN) for 4 repetitions (2h). Then we observed project 180-20 for 2 hours until it dropped to 30 deg elevation (the limit as stated in the readme file is 35 to 30 deg min). We returned to NGC3627 for 160-16 for the last hour - it was very close by to the 180-20 source.

Mar 18th, Thursday

03h - 09h; We first made a pointing + focus + beammap on 3C279 cat NIKA2R6; Then we have observed for project 181-20 : source RXJ1347 with 1 Nrep, then for project 107-20 : source L1689A with 1 Nrep. Then, at ~5h30 we switched to GASTON_dust project, with 1 Nrep on L1689B, and GASTON_GP with 2 Nrep on L23p9 and started 1 Nrep on L24p5.

09h - 15h; Chenlin: Excellent opacity, continuing on GASTON_GP, then 175-20 project and then 095-20. Acquisition crashed around 11AM LT. It was rebooted, one or two paintings affected.

15h - 21h; Continuing on 095-20, but the atmosphere is a bit unstable. Degrading fast in the end of the afternoon with very thick cloud coverage.
