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
