Daily Reports

We are going to call this run "Cryo 48 bis" and NIKA2 run 35. We are using the same ini files as for NIKA2 run 24, hence no change (we add "bis" only to specify that this is another pool). The reason of this choice is that we would like to be able to easily cross-calibrate the NIKA2 run34 with the data of this NIKA2 run 35.

Andrew arrived at the telescope. Florian and Longji are stuck at the Barcelona airport due to demonstrations. Stefano and Bilal are here since last week, already.

Afternoon shift (Bilal + Andrew + Stefano)

We start the pool in good weather conditions (tau~0.3), and everything is alright with NIKA2 after maintenance. We start with project 036-19 since the beam is still broad from the afternoon conditions and the PI is okay with it. At the end of the shift, we start observing 092-19 (source MOOJ2206)

Night shift (Stefano)

We take over, ok, I take over :-D and continue with the observation of MOOJ2206 (proj. 092-19). I perform 2.66 repetitions. Then tau increases above ~0.35 on avg, with instability spikes and I interrupt. Follows the usual set of calibrators. It's earlier than usual, but this way I can see how the sky evolves. The trend of tau to increase ceases. I go on with project 093-19 (2.66 repetitions of source XLSSC072). Then tau becomes too high and the target too low (3:45 UT). I switch to 028-19 (source B10) that is good for higher opacity and now is also below 80 deg elevation.

Morning shift (Andrew + Angel)

We take over at 6am with the telescope in focus and pointing well, and we continue to observe the Taurus B10 field for 028-19 until ~7:00 UT. Tau has been stable around ~0.4 for most of this time. We had a bit of trouble finding a suitable focus after sunrise, and then had some trouble communicating with the telescope. We finally resume observations for project 091-19 on MS0735 at ~9:00 UT.

Night shift (Stefano + Bilal until 23 UT)

After learning from Bilal everything I have never dared to ask about EMIR, tonight I enjoy some 1-pixel observations.

Morning shift (Andrew)

EMIR observations continue all morning, with tau varying between ~0.6 and 1.7. Florian and Longji finally arrive at the telescope. Weather conditions around a 225GHz tau of 1 and strongly varying aren't anymore suitable for EMIR@3mm backup projects. (CK)

Night shift (Stefano, Florian and Bilal)

Also tonight is dedicated to one-pixel joys This is becoming an EMIR pool.

Oct 18th, Friday

Morning shift (Andrew and Longji)

EMIR observations: tau is ~0.5 and we are struggling to find any suitable targets. By 8:30 UT, we can't find any projects that would like 3mm only, so observations cease for now.
