SHORT SUMMARY of PURPOSE:                                                
                                                                                
 Set up the "starting vector" for the Kalman filter from the pattern            
 recognition output.                                                            
                                                                                
LIST and DESCRIPTION of INPUT VARIABLES/ARGUMENTS:                       
                                                                                
 SSTART - the initial state vector (REAL*8 5-vector)                            
 CSTART - the covariance matrix (REAL*8 5*5 matrix)                             
 ZSTART - the z coordinate of the starting vector (REAL*8)                      
                                                                                
 Information in various Kalman filter common blocks                             
                                                                                
LIST and DESCRIPTION of OUTPUT VARIABLES/ARGUMENTS:                      
                                                                                
 Various common blocks are filled with the position of the start and            
 end points and the starting vector.
