Describe NK2013_Jun16 here.
Back to list of day to day logbook of observations
2013-06-16
- 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
- Quick description of the session 14h30 to 2h UT
- Calibration: Pointing, focus, otfgeom.
- Secondary calibrators: CRL618, IRC10216, GL490, (HLTau + L1551) with two Lissajous and one 10'x10' OTF, W3OH
- M82 2'x2' lissajous
- Skydip
- SZ on RXJ
- rhoOph
- CygA
- M33
- Faint sources to measure noise figures (20-40 mJy range at 1mm)
