* Andrea arrived at the telescope.
* Status of the Instrument:
- The cryostat is at the nominam temperature T_100mK=147mK - All the 20 feedlines are connected. - The acquisition works nominally (few problems in the morning concerning the ports closed in nika2) - We are producing normal,compressed and mini file on nika2 and mac12 during the night to check if they are right. First check is ok. We will keep checking tomorrow morning.
Hereafter some plot to check the good health of NIKA2:
Figure. Left: trace of the 1140 pixels of array 3; right: monitor with all the 20 boards tuned.
Figure. Noise with the window on respectively the 2mm, 1mm NIKEL_RF (array 1) and 1mm NIKEL_DC (array 3)
THE NOISE is taken with the window on the cryostat. It is in agreement with the previous observing campaign. No traces of the pulse tube.
