NK2012_S5
20120604 Final day
- Nasmyth offsets : 0, 0
- Set pointing : 0 0
- Set Focus : -2.4 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
- Crab: 16min OTF_15x10
- 0716+714 (pointing quasar): OTF_faintsource2012 (4 min), APM08279+5255: 5x OTF_faintsource2012 (20 min)
- 0923+392 (pointing quasar): OTF_faintsource2012 (4 min), F10214+4724: 5x OTF_faintsource2012 (20 min)
- 3C273 (pointing quasar): OTF_faintsource2012 (4 min), RXJ1347-1145: xxx OTF_RXJ (xxx6 min)
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)
Whole Freq Sweep with telescope at 45 deg. for B then A. around 14:26
