==== 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.''
