NSA/NIMFR/C2 - Tube heater problem

The tube heater was not keeping the tube quite as warm as we would like to see.  The 
function of the tube heater is to keep condensation from forming on the window.  Even though 
it wasn't working up to spec, it was still staying warm enough to keep condensation off.  
Maintenance resolved the issue.  It should be noted that some fluctuation is normal due 
to the very cold air temps this instrument operates in.

NSA/MFRSR/C2 - Shadowband misalignment

Instrument was experiencing shading problems. Because of the very low sun angles it is 
difficult to determine what ranges of data are OK.  Mentor suggests avoiding data covered by 
this DQR.
