SGP/TSI/C1 - Instrument failure
DataStreams:sgptsiC1.00, sgptsicldmaskC1.a1, sgptsiskycoverC1.b1, sgptsiskyimageC1.a1
Description:
The TSI-880 experienced a power and/or computer failure. It was replaced with a spare 
TSI-440 and data collection resumed 4/5/05.  Note: this is a temporary replacement.

SGP/TSI/C1 - Heater problem
DataStreams:sgptsicldmaskC1.a1, sgptsiskycoverC1.b1, sgptsiskyimageC1.a1
Description:
The TSI was converted from a model 880 to 660 which requires separate power for the mirror 
heater. The heater was not powered during this period so morning dew and other 
condensation was not quickly evaporated.

SGP/TSI/C1 - Contamination of mirror
DataStreams:sgptsimovieC1.a1, sgptsicldmaskC1.a1, sgptsiskycoverC1.b1, sgptsiskyimageC1.a1
Description:
A persistent bird was landing on and polluting the mirror, multiple times throughout the 
day. Spikes were placed on the corners and top of the instrument (an affective deterrent 
in the past) but this bird had the agility to perch on the top-center of the mirror.
