Subject:
SGP/SIRS/E13 - Reprocessed: Incorrect UIR calibration
DataStreams:sgpsirsE13.b1, sgpsirs20sE13.a0
Description:
For the time range specified the UIR had incorrect calibration coefficients applied.  The 
k1 coefficient applied was 0.25042 when it should have been 0.2558.  This resulted in the 
instrument under reporting up_long_hemsip by approximately 2.1%.
