2015-10-12
Following not updated
.Cryostat Temperature: 170mK cooling down slowly 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.
