|
C
|
|
C Procedure reads photo-ionization cross sections fit coefficients
|
|
C based on Opacity-Project (OP) data from file RBF.DAT
|
|
C Data, as stored, requires linear interpolation.

C Meaning of global variables:
|
|
C NTOTOP = total number of levels in Opacity Project data
|
|
C IDLVOP() = level identifyer of current level
|
|
C NOP() = number of fit points for current level
|
|
C XOP(,) = x = alog10(nu/nu0) of fit point
|
|
C SOP(,) = sigma = alog10(sigma/10^-18) of fit point
|
