NK2012_S4

20120603

Nasmyth offsets : 0, 0

Set pointing : 24 9

Set Focus : -1.3 mm

df (Frequency modulation is 10kHz)

Cryostat cold at 95 mK.

New configuration of resonances for both arrays. (Pixel numdet 127@1mm could now be pixel 120+18, 7@2mm should still be 7)

Base frequencies changed to 1.322000 @2mm, 1.957680 @1mm

Track means automatic retuning of resonances
