Describe NK2013_Jun15 here.

Back to list of day to day logbook of observations

2013-06-15

  • Cryostat Temperature: 220mK after recycling yesterday .
  • 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

For start:

  • Working with the new pointing model (rms went from 5 to 2 arcsec for yesterday pointing session)
  • Nasmyth offset 28, 28 implemented in the pointing model
  • offset 0 0 /system nasmyth
  • Quick description of the session 14h30 to 2h UT
  • Calibration: 3C84, 3C279 Pointing, focus, otfgeom.
  • Secondary calibrators
  • Venus/Saturn sidelobe measurements
  • Bright extended source(s): Crab, NGC2023, OrionLBS
  • Skydip
  • Arp220
  • Faint sources to measure noise figures (20-40 mJy range at 1mm)
  • SZ on RXJ
