SGP/QCRAD/E10 - Tracker failure
DataStreams:sgpqcrad1longE10.s1, sgpqcrad1longE10.c2, sgpqcrad1longE10.s2, sgpqcrad1longE10.c1
Description:
During the night of 11/05-06 2004 the tracker failed at this location. During CM on 12/01, 
power cycling returned the tracker to service. However, tracker was not properly 
tracking in the AM. Tracker failed again sometime near 01/01/2005.	CM reloaded the tracker 
program and realigned the tracker on 01/26/2005 1600GMT correcting the problem.

Documented in instrument DQR: D041206.1
Suggestions: 
Don't use SW direct or diffuse data during these time periods. If 

"source_BestEstimate_down_short_hemisp" is 0, don't use Best Estimate GSW data. Note that fewer quality 
checks can be applied accurately to the BestEstimate data.
