Back to list of day to day logbook of observations

2014-01-20

Cryostat Temperature: 150mK (regulated, RMS ripple 0.03mK).
Arrays status tonight: pixels 2mm - xxx noise; XX pixels 1mm xxx noise (to be determined)

Modulation frequency: 8kHz 1mm, 5kHz 2mm

Opacity is measured with the new taumeter at 225 GHz

Nasmyth offsets : 0, 0

Set pointing : 0, 0

Set Focus : -2.40 mm

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