NIKA2 run 6 26 October 2016

Back to list of day to day logbook of observations

2016-10-26

Cryostat Temperature: 180mK (regulated with heater).
Arrays status tonight: Array1 about 30 bad out of 1060, Array2 about 3 bad out of 580, Array3 about 30 bad out of 1045
Noise seems fine: no appreciable PT effect
Tau is really very high: we start with the window on cryo and try to move the telescope around --> dark tests!
Modulation of frequency: 4kHz for Array2, 8kHz for Array1 and 3
Quick description of the session: just dark tests, a priori..
