SGP/MFRSR/E11 - Alignment and heater board

Instrument had a shading issue since reinstallation after calibration. Additionally, the 
heater controller failed on 20091121.  Prior to the heater controller failure, data from 
sunrise until 1800 UTC were fine.  After the failure, no data should be used.  Maintenance 
on 20091202 resolved both the alignment and heater controller issues.
