Describe NK2013_Jun13 here.

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:
