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:
