Describe NK2013_Jun12 here. NIKA November 2012 S2

Back to list of day to day logbook of observations

2013-06-12

  • 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 measured with the new taumeter at 225 GHz

For start Nasmyth offsets : 28, 28

Set pointing : 0, 0

Set Focus : -2.40 mm

  • Quick description of the session:
  • Mars Pointing, focus, otfgeom.
  • 4 sources at different elevation to check the nasmyth corrections. If ok, correct pointing model
  • Mars, pointing focus, otfgeom
  • Pointing session for 3h
  • Mars OTFgeom at 3 foci, 5 lissajous focus, 6 lateral positions
  • Secondary calibrators: pointing, otf_3x3, faintsourceLissajous
  • skydip
  • faint sources to finish for noise measurements
