where ka_k<kb and qa<chi/pi<qb. The C_SP00, C_SC00, etc are the 
coefficients for the shear stress p_{\chi\eta} at y=0. 

For example, in 0250t21.dat, 

   8   7  0.5000E-01  0.2000E+02  0.0000E+00  0.1000E+01  0.2500D-01  0.5000D+00 160

  0.155479E-04, -0.395571E-05,  0.451193E-05,  0.368411E-05  &

means: 

  Nm=8, Nn=7, range 0.05<k<20 and 0<chi/(2pi)<1, c=0.05, epsilon=0.5
  C_P00= -0.373612E+00, C_C00= -0.119152E+01, ... ...

----------
how to use this
----------
To generate the subroutine for, e,g. (c,epsilon,Ta,Tb)=(0.05,0.5,1,2),
replace the contents of the data statement "data/.../" in 0250t21.f90 
by the contents of 0550t12.dat with deleting its first line. 
See the header in 0250t21.f90.
