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 : -1.3 mm (not at all optimised)

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