Describe NK2013_Jun12 here. NIKA November 2012 S2
Back to list of day to day logbook of observations
2013-06-12
- Cryostat Temperature: 216mK (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 Nasmyth offsets : 28, 28
Set pointing : 0, 0
Set Focus : -2.40 mm
- Quick description of the session:
- Mars Pointing, focus, otfgeom.
- 4 sources at different elevation to check the nasmyth corrections. If ok, correct pointing model
- Mars, pointing focus, otfgeom
- Pointing session for 3h
- Mars OTFgeom at 3 foci, 5 lissajous focus, 6 lateral positions
- Secondary calibrators: pointing, otf_3x3, faintsourceLissajous
- skydip
- faint sources to finish for noise measurements
