      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 and where to find the corrected data.                  
                                                                      
      It was discovered during the Mars Express mission that for IFMS 
      the file naming convention of AGC (Automatic Gain Control) raw  
      files was crossed since beginning of that 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.
