SGP/SIRS/E31 - Tracker failure

All tracker related datastreams are affected: short_direct_normal (NIP), 
down_short_diffuse_hemispheric (8-48), and possibly the down_long_hemisp_shaded (PIR) although it is not 
apparent in the reviewed data for the affected timeframe.

SGP/SIRS/E31 - Reprocess: Incorrect calibration coefficients

During the time range specified the UIR and DIR serial numbers are correct but incorrect 
calibration coefficients were applied in the datalogger.  The incoming longwave UIR and 
DIR must be recomputed using the new k1 calibration coefficient supplied and applied to the 
raw data in the corresponding SIRS 20s datastream. The start time corresponds to the 
first available data in the Archive.  However, repro job should start on first available 
data from the station.
