SGP/SIRS/E12 - Shadowband misalignment
DataStreams:sgpsirs20sE12.a0, sgpsirsE12.b1
Description:
The E12 tracker had failed from 7/20 to 8/2. The tracker was replaced and returned to 
service on 8/2.  However, the tracker was not aligned correctly until 10/18.

bad and not recoverable during this entire time range.
