MAO/SKYRAD/M1 - Reprocessed: IRT configuration error

SKYRAD IRT sky temperature measurements were ~40K too low. The analog output configuration 
of the IRT was automatically set to incorrect values by the serial collection script. An 
error in the name of the startup file was corrected.

The data were reprocessed to correct the configuration/calibration and the reprocessed 
data were archived in February, 2014.

calibration coefficient K1= 0.247520; PIR2 SN34306, calibration coefficient K1=0.230410.
PIR SN34306 (on sun tracker) was used with K1= 0.247520 on the PIR1-DIR datalogger 
channel; K1=0.230410 should be used for reprocessing to provide correct data for PIR1-DIR 
parameters.
