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)
