Back to list of day to day logbook of observations
2013-06-13
- 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
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
Set pointing : 0, 0
NEW and definitive pointing model determined from yesterday
Set Focus : -1 mm
- 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
