description
Value of the actual IFG sensor temperature [SensorT] when available, otherwise a MLST 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.

description
The actual IFG electronics temperature (ET) is only available a few times per SOL. Since a value is required for every IFG vector for calibration purposes, a spline fit to the PAE temperature T-0014 is 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 are 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. This value is given in units of degrees Celsius.
