== Goals of the run ==

Continue the commissioning started in run 5 and continued in run 6:<<BR>>
 * '''Open the cryostat, change the array 1 corrugated lens with the old smooth lens to see if the flat field (gain) gradient we observe since run 5 on this array is due to a problem with the corrugated lens'''.
 * After cooling down the cryostat few hours of tests on sky to check wether everything is OK or if we need to warm up to fix something inside the cryostat.
 * Given the operations done during phase 1 of the run (Jan 10-12), namely 5mm drop of the 50K optics block which was too high, and tightening the M6 stop screw (+ implementation of the pneumatic actuator before the Feb phase 3), need to redo the alignment (laser for pointing + ecosorb for pupil alignment), and then the pointing model.
 * Start real test observations in February: again '''perform the scans which are the most useful for commissioning: stack more beam maps at various focus (Z,Y,X), various elevation and various scan orientations.'''
 * Continue to monitor regularly secondary calibrators to check stability of the instrument gains.
 * Continue any necessary work on detectors working point, electronics, acquisition, synchronizations, data files... monitoring possible effects on the beam maps.
 * Continue all necessary calibration scnas (pointing, focus, skydips...)
 * In parallel to beam maps, test deep integration on well known sources to show reproducibility in reaching the rms expected.
 * Map extended features (see previous run).
 * Start polarization commissioning.
