Describe NK2013_Jun17 here.

Back to list of day to day logbook of observations

2013-06-17

  • Cryostat Temperature: 220mK .
  • Arrays status today: 192 pixels 1mm ; 128 pixels 2mm
  • Modulation frequency: 8kHz 1mm, 4kHz 2mm

Opacity is measured with the new taumeter at 225 GHz

Wind is still quite strong but better than during all night (antenna stopped) For start:

  • Working with the new pointing model
  • Nasmyth offset 28, 28 implemented in the pointing model
  • offset 0 0 /system nasmyth
  • Quick description of the session 12h30 to 8h30 UT
  • Calibration: Pointing, focus, otfgeom.
  • Secondary calibrators:
