GRW/MWR/M1 - Loose mirror

The data from the MWR were suspicious and became progressively worse. The problem was 
traced back to the fact that the screw that keeps the mirror in place had become loose and 
the mirror was freely rotating. 

The mirror was tightened on 6/9/2009, however the measurements were noisy until 6/16, when 
the instrument was rebooted and all the connections checked. 

Measurements between 5/1 and 6/9 should not be used. Data between 6/9 and 6/16 are usable, 
although they are very noisy.
