Subject:	SGP/IRT/C1 - UPS failing
DataStreams:	sgpirt10mC1.b1
Description:	The IRT data were intermittently bad during this period due to a failing UPS. The problem was corrected by replacing the UPS.
Measurements:	sgpirt10mC1.b1: internal_voltage Surface Infra-Red Temperature Maxima(sfc_ir_temp_max) sfc_ir_temp_std Surface Infra-Red Temperature Minima(sfc_ir_temp_min) Effective Surface (Skin) Temperature(sfc_ir_temp)

Subject:	SGP/IRT/E11 - Response time
DataStreams:	sgpirtE11.b1, sgpirt200msE11.a1
Description:	The time response of the temperature measurement was changed from 1.0 to 0.1 sec to accommodate the 5Hz sample rate. This caused a 370% decrease in the resolution (to 1.85C at a sky temperature of -50C) and a significant decrease in the signal-to-noise ratio.
Measurements:	sgpirtE11.b1: sky_ir_temp_std ref_ir_temp_std sgpirt200msE11.a1: Temperature, Sky Infra-Red(sky_ir_temp) ref_ir_temp
