NIKA November 2012 S1

Back to list of day to day logbook of observations

2013-06-11

  • Cryostat Temperature: 216mK (naturally set by settings of 3He circulation [no heater] trying to mitigate oscillation due to leak).
  • Arrays status tonight: pixels 2mm - xxx noise; XX pixels 1mm xxx noise (to be determined)

Modulation frequency: 8kHz 1mm, 4kHz 2mm

Opacity is measurd 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.
