Daily Reports

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

A couple of preparatory notes by Stefano:

• please use the PIIC monitors. If you notice that one (or more) of the PIIC monitors stop processing the data, please notify the AoD: it is possible that the scripts that produce the IMBFITS files have stopped.
• please take numerous calibrators scans, also in bad sky conditions (as long as NIKA2 is used): for example take one calib scan whenever the pointing/focus source is a calibrator. This will help the analysis of the calibration. Thank you in advance.

Little extra by Stefano: I would have liked to be at the telescope to celebrate the 50th pool of NIKA2 with a special mid-night pasta, but unfortunately it is still not possible. Therefore I have prepared a little surprise. I hope it can make you smile in these eerie times. Stay Safe!

03h - 09h; Sergio (Op.), Angel: Checking the telescope at 05h (LT). Opacity ~0.8. NIKA2 Pool targets according to these conditions are too low. Switching to EMIR backup project 171-20. Pointing/focus OK. Wobbler required, but it doesn't work after several tries. Switching to NIKA2 at ~7 am. Resonances reloaded. Opacity ~0.65. Pointing/focus on K3-20A. Despite the opacity level, conditions look quite stable. Trying to restart the data-filler of TAPAS; it doesn't work (waiting for Computer Group instructions). NGC7027: calib_1scan (s32). Then, a skydip. Monitoring stability; large spikes of opacity.

09h - 15h; Antonio, Emmanuel, Bilal: stopped ~1h for technical tests of wobbler system. Observed with NIKA2 for project 126-20.

15h - 21h; Angel: Observed 12 fields of 126-20, and started with EMIR backup program 109-20 at 20h (LT); tau~0.7, unstable. Data records still being recovered in TAPAS.

21h - 03h; Annie, Carsten take over to continue with EMIR projects, first 109-20. Tau~0.7. Some clouds. At UT00:00 change to EMIR 097-20 154.05+5.07. Tau drops to 0.5. TAPAS working.

Feb 12th, Friday

03h - 09h; Miguel, Angel: Starting with opacity ~0.8; large instabilities. Continuing with EMIR backup programs: 171-20. Four bright targets observed. The opacity at the end of the shift dropped quickly to ~0.3. Switching to NIKA2 at 08:45. Resonances reloaded after that. TAPAS takes more time than usual to update the records: reported to IRAM's Granada User Support.

09h - 15h; Laurence, Miren: Starting with opacity at ~0.3, increasing. Focus on NGC7027. Difficult to get a good pointing, clear indication of atmospheric instabilities. Whenever we obtained "reasonable" pointing, we did calib_1scan scans on the three secondary calibrators (MWC349, NGC7027 and CRL2688). The quality of these observation is uncertain. To be repeated. At ~ 11h (LT) start with 126-20 project, one repetition toward 4 different GP fields. Opacity drops and after focus and pointing, we change to 199-16 and performed 2 repetitions on PSZ2G104 (dubious atmospheric stability). We probed atmospheric condition toward the opposite azimuth: better focus and pointing. We moved back to 199-16 but choose another target close to this azimuth: 3 repetitions on ACTJ2302. The atmosphere was stable at the end of our shift.

15h - 21h; Isabelle, Karine: At the begining of the shift, tau was very good (~0.15) and the atmosphere stable. We started with a focus, pointing, beammap, and a calib_1scan on Uranus. We then observed project 094-20 (5 Nrep on L1506). We then did a skydip and continued on project 094-20 observing G150 (5 NRep). Tau was ~ 0.2 by the end of the shift and the atmosphere stable all over the shift.

21h - 03h; Golshan, Carsten: 160-16: NGC3198 (2h) then NGC5194 (2h), tau~0.2-0.28, stable with <+/-6Jy, rms~2Jy. Pointing, Focus stable. 1 skydip. Tau prediction page failed (saying 502 Bad Gateway)
