        Time periods may be specified only for the highest order coefficients   
        used (i.e. if Ga and Ga dot are used, only Ga dot can have time         
        intervals). When using time periods the number of ACCEL cards           
        required is equal to the number of time periods plus the order (order   
        = the number in column 8 +1). The Ga, Ga dot, and/or Ga double dot      
        without a time interval are used for times beyond the end of the        
        the last interval specified on the ACCEL cards. See following           
        example.
