    Seltzer & Berger's data (brems01 ~ bremes10) are decomposed into
    each element ranging from Z=1 to 100.
    The data file name is
        SZ1, SZ2, ... SZ100
    corresponding to  Z=1, Z=2,...Z=100.
 
     The format of each line is
      
        v   cross-section  Ek

    where
         v = Eg/(Ee-me)
         cross-section = (beta/Z)**2 v ds/dv (mb)
         Ek = Electron kinetic energy in GeV

    The upper energy may be specified. (GIVE Emax)

    You can inspect each data file by gnuplot

****   unpack.f

     This is almost the same as seeData.f
     Difference is that the files name created is Z1~Z100
     Each file containes only cross-section values.

     The files  Z1 ~Z100 are used when making sampling tables.


     The upper energy may be specified. (GIVE Emax)

     Emax = 4001.
