Describe NK2013_Jun13 here.
Back to list of day to day logbook of observations
2013-06-13
- Cryostat Temperature: ???mK (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 Working with the new pointing model (rms went from 5 to 2 for yesterday pointing session) Nasmith offset 28, 28 implemented in the pointing model
Set pointing : 0, 0
Set Focus : -2.40 mm
- Quick description of the session:
- Mars Pointing, focus, otfgeom.
- Secondary calibrators
- Bright extended source(s): Crab, NGC2023, OrionLBS
- Skydip
- Arp220
- Faint sources to measure noise figures (20-40 mJy range at 1mm)
- SZ on RXJ
