SGP/MWR/B6 - Reprocess: Incorrect calibration
DataStreams:sgpmwrtipB6.a1, sgpmwrlosB6.b1, sgpmwrlosB6.a1
Description:
When the operating software was upgraded, the automatic calibration routine was, for some 
unknown reason, initialized wrong. The problem was corrected when the site operator 
stopped and restarted the software.  The data need to be reprocessed with the correct 
calibrations coefficients.
