NIKA October 14th, 2015 / S1

Back to list of day to day logbook of observations

2015-10-14

Following not updated

.Cryostat Temperature: 170mK cooling down slowly Arrays status tonight: full 2mm array - 1-3 Hz noise; 2 feed lines on 1mm array 3-5Hz noise Modulation frequency: 10kHz 1mm, 5kHz 2mm

For this session Array 3 is not connected.

Opacity is measured with the new taumeter at 225 GHz

Nasmyth offsets : 0, 0

Set Focus : we start at 0.0 mm

Quick description of the session: beam map.
