      Most notably it was discovered that the incoming Doppler data from ESA 
      and thus level 1a and level 1b Doppler data may contain a wrong uplink 
      frequency. 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.
