SGP/MFRSR/E13 - Reprocess: Angstrom Exponent Error

The data used to calculate the angstrom exponent was incorrect.  These
fields should not be used.  All other fields are considered good.

• Angstrom exponent(barnard_angstrom_exponent)
• Angstrom exponent(michalsky_angstrom_exponent)

SGP/MFRSR/E4 - Complete filter function info unavailable

At this site we do not have complete filter function information.  Currently only the 
central wavelengths are available, and this will be the case unless more complete information 
on the head becomes available.  Data are not affected.

SGP/MFRSR/E13 - Shadowband misalignment

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).

This final adjustment seems to a solved the problem!
