NIM/MFRSR/S1 - Shading problem

A shading problem was first noticed in Aug data.  Subsequent careful examination of prior 
data indicate it may have begun in early July.  Because of the near constant dusty 
conditions, it is difficult to determine exactly when it started.  As such a loose start date 
of 7/1/2006 is given to this DQR.  There is reasonable evidence of shading issues in the 
second half of July.  The hours in question are between 1430 and 1700 UTC.  Mentor 
suggests avoiding data during these hours.  Maintenance on 10/25 resolved the problem.
