Subject:
TWP/QCRAD/C2 - Tracker failure
DataStreams:twpqcrad1longC2.c1, twpqcrad1longC2.c2, twpqcrad1longC2.s1, twpqcrad1longC2.s2
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.

Several of these periods are documented in instrument DQRs:

D110831.1, D090328.1, D081222.3, D040107.1, D011207.1, D011019.8
