NIKA October 10th, 2015 / S1

Back to list of day to day logbook of observations

2015-10-10

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

Opacity is measured with the new taumeter at 225 GHz

Nasmyth offsets : 0, 0

Set Focus : we start at -2mm (not at all optimised, first task is try to improve on this!)

Quick description of the session: Test the Pako sequences and data flows.
