SGP/MFRSR/E16 - Instrument shading problem

A shading problem, initially it is very minor, but grows progressively worse until 
maintenance resolved the issue.  During April and May it is minor enough that most users can 
likely use the data without issue.  On 5 June the shading becomes suddenly much worse, and 
from this time on users would certainly want to screen the data between sunrise and 1630 
UTC.
