This problem was identified during processing and corrected for level 2 data. If this problem occurred the folder UPLINK_FREQ_CORRECT will be generated in the CALIB directory containing information which raw files were effected and where to find the corrected data. It was discovered later in the mission that for IFMS the file naming convention of AGC (Automatic Gain Control) raw files was crossed since beginning of the mission. In fact AGC1 refers to D2 and AG2 refers to D1 and not the other way around as it should be. Consequently the AGC files were swapped during the whole processing. Anomalies which ocurred during measurements such as wrong sample rate or wrong timing which might affect the quality of the data are listed in CATALOG/DATASET.CAT under anomaly report near the end of the file.
