OP Computations of Rosseland mean opacities
Mass-Fractions Metal Fractional Composition (default = S92)
Hydrogen Mass-Fraction (X)
Metal Mass-Fraction (Z)
Note: metal abundances are re-normalised to the value of Z which has been set --- it is necessary to specify only the relative abundance for each metal. A negative abundance implies that the element is included in the mixture but its opacity is excluded.

Output options
RMOs and their derivatives for a given temperature-density mesh. The mesh can be specified by a range or a tabulation of {log10(T) , log10(ρ)} or {log10(T) , log10(R)} where T is the temperature in Kelvin, ρ the density in g cm-3 and R=ρ/T63, with T6=T*1.E-6.
Please choose ONE of the following output options:
 
An intermediate opacity file that can then be used locally for interpolation (temperature-density) with the code opfit.tar.gz.
