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 arcsec for yesterday pointing session)
Nasmith offset 28, 28 implemented in the pointing model

Set pointing : 0, 0

NEW and definitive pointing model determined from yesterday

Set Focus : -1 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
