MORS_0203   The MCH directory mistakenly contains CSV7252A.MCH and its label. 
              Although these are permitted under the design in MGSRSSIS.TXT,  
              CSV files from engineering data are not included in this        
              volume, nor are CSV files planned for other volumes.

MORS_0213     engineering data (ECH) were only partially acquired because of  
              NERT Cache, NASCOM line, and/or SOPC hardware problems.  Some   
              DSN Monitor data were also truncated for the same reason.       
                                                                              
MORS_0217   1997-10-20 (97/293) engineering and monitor data were lost through
              an operations error at Stanford.  1997-10-23 (97/296) through   
              most of 1997-10-26 (97/299) engineering and monitor data were   
              lost because the NASCOM line went down.                         
                                                                              
MORS_0221   File 7302310L.SFO in the SFO directory is a bogus file.  The      
              same data are in 7302310B.SFO on MORS_0219.                     
                                                                              
            Keyword WSE_FILTER added to queries for engineering data starting 
              97/310; removes "bad records" which caused apparently toggling  
              of data in channels L-0061 and L-0091.
