Subject:
SGP/SASHE/C1 - Temperature controller disabled
DataStreams:sgpsashemfrC1.b1, sgpsashevisC1.b1, sgpsashevishisunC1.a0, sgpsashenirC1.b1,
sgpsashenirhisunC1.a0
Description:
After servicing of the SASHe on Dec 20, 2013 a temperature controller was left in a 
stand-by mode.  The situation was corrected slightly before 20:00 UT on Jan 14, 2014.  Both the 
"vis" and "nir" spectrometers have some potential for temperature sensitivity but the 
impact should not be severe given that the system is housed within a climate controlled 
building and the temperature gradients are small.
Suggestions: 
The MFRSR, NIMFR, and RSS are possible substitutes for the SASHe measurement.
