           Note: Observation start time in the observ.tx file                   
           was incorrect.  File initially tried to start at                     
           09:08 when the previous observation ended.  I                        
           stopped it a few minutes after that, edited the                      
           file to reflect the correct times, and also re-sent                  
           the crd files, in case they were old versions with                   
           incorrect start times as well.
