Since a value is required for every IFG vector for calibration purposes, a spline fit to the PAE temperature T-0014 was used as a proxy. T-0014 is sometimes available every minute or so, but is only infrequently returned at night. The observed values of T-0014 were spline fit to produce data set that is sampled at 5 minute resolution or better and then the values between those samples are derived by linear interpolation. After 2019-11-18, ET data became available every 15 minutes and data were linearly interpolated between samples to provide continuous data. This value is given in units of degrees Celsius. See the IFG calibration document for additional details. 9999.999 modelST 13 147 ASCII_Real 9 %9.3f Degree Value of the actual IFG sensor temperature [SensorT] when available, otherwise a LST and UTC dependent model of the IFG sensor temperature [deg C] derived from the measured values from selected time intervals is provided. The FIR filter applied to the temperature data is longer than the one applied to the MAG data so there is a roughly two hour gap in the temperature data whenever the IFG powers on (i.e. following a spacecraft safing or PAE reset). The value in this column is used for the MAG calibration since it is available for all samples. See the IFG calibration document for additional details. 9999.999 modelSA 14 157 ASCII_Real 9 %9.3f A LST and UTC dependent model of the fixed solar array current [A] derived from the values of the E-0771 from selected time intervals.
