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. The corresponding Level 2 files contain already the corrected uplink frequency and can be used for further processing as usual. 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. If the number of data sets exceeds 999, the VOLUME_ID contains a letter in its 4 digit sequence number. It is: A = 10, B = 11, C = 13,... For instance a VOLUME_ID RORSI_2A50 represents the 1050th gravity data set.
