Back to list of day to day logbook of observations

2012-11-18

Cryostat Temperature: 150 +/- 0.02 mK (regulated with power 50uW)
Arrays status tonight: 126 pixels 2mm - good noise; 8 pixels 1mm noise should be good (reduce the number of pixels so that total tones power below amplifier saturation).

Nasmyth offsets : 0, 0

Set pointing : 0, 0

Set Focus : -1.9 mm

Quick description of the session: Proceed with the observing procedures (see ListOfAstroTarget2012N5): geom, pointing cross, focus, etc. (e.g.check plateau on strong sources) then fainter and fainter sources to check sensitivity.
