QUaD Observing Strategy Whole telescope 7.5 deg azimuth scan as modulation on top of sky track (at Pole sky rotates around zenith) Scan 5 times out and back - then step in el by 0.02 deg and repeat. Build simple raster map - no cross linking! Scan at 0.25 deg/sec putting ell range 200 to 2000 at 0.1 to 1Hz in timestream. One run per day starting always at same LST (5 hour fridge cycle) (Start as telescope clears lab building) Cal, 8 hours CMB, cal, rotate telescope, cal, 8 hours CMB, cal
