Subject:
SGP/SIRS/E21 - Shadowband Misalignment/Tracker Failure
DataStreams:sgpsirsE21.00, sgpsirsE21.b1, sgpsirs20sE21.a0
Description:
The solar tracker failed beginning around sunrise on 05/19/03 most likely during the 
previous nights reset. Failure time was approximate time of sunrise at 1000 on 05/19/03.  The 
tracker was power cycled and RTS at 1415 GMT on 05/28/03.
Suggestions: 
Bad data is not recoverable for tracker mounted instruments (NIP-direct shortwave 

,PIR - downwelling longwave, 8-48 - downwelling short diffuse)
