 [2]    If the degree and order on the SSCOEF card must be less then or         
        equal to the maximum degree and order as input on the SSTOPO card.      
                                                                                
 [3]    If it is desired that the starting values of coefficients be different  
        than the a priori values for those coefficients then the SSCOEF card    
        should be used as follows:                                              
                                                                                
        o    SSCOEF cards requesting the desired coefficient adjustments        
             should be included in the setup deck.  The a priori values         
             will be indicated on these cards.                                  
                                                                                
        o    For each coefficient pair for which the starting value is to       
             be different than the a priori value, an additional SSCOEF         
             card should be in the setup deck.  This SSCOEF card will           
             indicate the starting value and come later in the deck than        
             the corresponding SSCOEF card requesting adjustment.
