                  cover this fixed time interval, `intlen'. 
 
   n              Number of sets of Chebyshev polynomial coefficients 
                  for coordinates and their derivatives (number of 
                  logical records) to be stored in the segment. 
                  There is one set of Chebyshev coefficients for each 
                  time period.
