NK2012_S5
20120604 Final day
Nasmyth offsets : 0, 0
Set pointing : 28 9.1
Set Focus : -1.5 mm
df (Frequency modulation is 10kHz)
Cryostat cold at 93 mK.
Configuration of resonances for both arrays similar to yesterday.
Base frequencies changed to 1.322000 @2mm, 1.956670 @1mm
Freq/bin: 1.869 kHz
dac: 3dB
Attenuation HF: 16 and 3 dB
Modulation frequency: 10 kHz
Track means automatic retuning of resonances
Observation planning:
- Stall position: open trap to let the big box out. Complete freq sweep near Mars:
- 1 tone config. Pointing, Pointing, Focus, Pointing, OTF_geomfast All tone config: Pointing, Pointing, Focus, Pointing, OTF_geomfast, Skydip
Cryostat closed: Complete frequency sweep on B (twice) at 12h55m45, A: 13h16
Starting configuration: Alain gone down on bike (Martino on his own with NIKA!), one tone only on each channel KA007(nd7,rz8), KB005 (nd126,rz7)
