      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 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.
