NIKA November 2012 S1
Back to list of day to day logbook of observations
2013-06-11
- 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
Nasmyth offsets : 0, 0
Set pointing : 0, 0
Set Focus : -2.40 mm
- Quick description of the session: Test the Pako sequences and data flows.

Juan put Nasmyth offset to 0 in pointing model; this is our starting point before the session ; tuning during the scan |

looks like some resonances still lost, do manual sweep to ge them back while otf being processed and analyzed |
