ISMREDTEC Reduced TEC measurements
This log outputs the 60 second reduced TEC measurements. Each log contains TEC and delta TEC
measurements at 15 second intervals, for a total of 4 measurements over a one minute span. Please see
the description of the ISMRAWTEC log for the definition of the TEC and delta TEC measurements.
The TEC data contained in this log have been carrier smoothed using a Kalman
filter.
