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. Possibly contains one of the files, which are listed in the Sorce_Product_ID in LEVEL02, files, which do not belong to the measurement. These files were only used for processing. Therefore one cannot find according LEVEL02 files. These, for the processing used files, do not affect the LEVEL02 files.
