      Data relating to the asymptotic packages RPROP and CFASYM are
      input via NAMELIST /BPROP/

      Namelist input /BPROP/

        The format of the following is 
       (Name, Type, Dimension, Default, Limits, ! description)
        Unless specified otherwise, the default value applies to all elements
        of array variables.

                           else function propagation)
             1 = alternative ( do not use this in bound state calculations)

             propagation
     
        NRANGE    I   1      0        [0:]
           ! number of subranges in R-matrix propagation. If zero then 
             code decides how many to use

        RAF       R   1    RMATR      [:]
           ! radius at which continued fraction method can be used
