NIKA November 2012 S3

2012-11-16

Cryostat Temperature: 150 +/- 0.02 mK (regulated with power 50uW)
Arrays status tonight: 126 pixels 2mm - good noise; 90 pixels 1mm noise 2x optimal (limited number of pixels and excess noise due to cold amplifier saturation --> -62dBm per KID instead of -50dBm).

Nasmyth offsets : 0, 0

Set pointing : 0, 0

Set Focus : -1.9 mm

Quick description of the session: One last test on the DYI Pako scripts(didn't worked well the previous days). Proceed with the observing procedures (see ListOfAstroTarget2012N5) but stopped by wind.
