I have a file that kinda look like:
 Input file :freq_map.in                                              

 beta_x =      0.427 alpha_x =      0.2705
 beta_y =      0.011 alpha_y =     -0.0055
  eta_x =      0.011  eta_xp =     -0.0035
  eta_y =      0.000  eta_yp =      0.0143
  !
                       phase space at IP at start                     
phase space at IP at turn n
     x            xp          y         yp            dl         dE/E 
turn    x            xp          y         yp            dl        
dE/E

  0.2000E-02  0.0000E+00  0.2000E-02  0.0000E+00  0.0000E+00 
0.5000E-03         2 -0.4532E-03  0.6929E-02 -0.1514E-05  0.4522E-03

...

I just want the columns of numbers for data analysis so that i will
have a table with columns of numbers. i don't need all the other
characters. I know i should use ReadList[], but i have no idea how to
do so. Any help would be appreciated. Thanks.
