SGP/MFRSR/E13 - Shadowband misalignment

Description:
The E13 MFRSR developed a shading problem on or about 05/04.  (The exact date when this 
problem started is difficult to pin down exactly.) The shading problem is easy to identify 
on a clear day because plots of direct beam and diffuse irradiance versus time become 
"fuzzy".  The total irradiance is not affected.
  

In response to the shading problem, a whole sequence of events then ensued: these actions 
were designed to solve the shading problem but did not succeed until the very end.

Here's a rundown of what took place:

98/05/11 - shadowband adjustment was made at 1544 GMT
         - this adjustment corrected the shading problem that 
           occurred in the morning, but inadvertently caused
           a PM shading problem 
98/05/20 - shadowband adjustment at 1804 GMT
98/05/21 - shadowband adjustment at 1630 GMT
98/06/01 - shadowband adjustment at 1910 GMT
98/06/02 - shadowband adjustmnet at 1550 GMT

Alas, these adjustments did not solve the shading problem and
it seemed to get worse (for example, on 06/11 the shading 
is VERY BAD from sunup until about 1500 LST).

98/06/16 - shadowband adjustment at 1715 GMT

This final adjustment seems to a solved the problem!
