Subject:
SGP/QCRAD/E21 - Tracker out of alignment
DataStreams:sgpqcrad1longE21.s2, sgpqcrad1longE21.s1, sgpqcrad1longE21.c1, sgpqcrad1longE21.c2
Description:
Tracker appears to be out of alignment or inoperative during these times. The 
short_direct_normal (NIP) and down_short_diffuse_hemisp (8-48) data appear to be bad and not 
recoverable.

Some of these dates are documented in instrument DQRs:

D030529.3, D030612.1, D030722.2, D040229.2, D080602.2, D080722.1
Suggestions: 
null
