MORS_0411  The high-gain antenna (HGA) azimuth gimbal became stuck late on    
             1999/105 or early on 1999/106.  A full set of spacecraft         
             engineering data for 1999/106 was not obtained until several     
             days later.  The original engineering data are in                
             ECH/9106106A.ECH while the later version is in ECH/9106106B.ECH. 
             There are corresponding versions of the CSV files.  No           
             additional data was found for either days 105 or 107.            
                                                                              
           For several days following the HGA anomaly, radio occultations and 
             tracking were spotty.  Typically the spacecraft low-gain         
             antennas were used, the transponder was in 2-way mode, and       
             telemetry was on.                                                
                                                                              
MORS_0413  First CD containing Antenna Gimbal Kernel (AGK) files; files       
             covering 1999-03-29 through 1999-04-28 were included on this     
             volume.  First CD containing Antenna SPK (ASP), Hinge CK (HCK),  
             and Text Frame Kernel (TFK) files -- all in the CALIB directory. 
             SIS changes covering the ASP, HCK, and TFK files were not        
             completed in time to be included with this volume; see MORS_0414.
                                                                              
MORS_0416 File AMD/9126127A.AMD (ORIGINAL_PRODUCT_ID = amdgen.99-127_2.out)   
            has an incorrect STOP_TIME in the label. Stop time should have    
            been 10:13:12.000.  The error was corrected and a revised file    
            (with the same ORIGINAL_PRODUCT_ID) became AMD/9126127B.AMD on    
            MORS_0417.
