OP Computations of Rosseland mean opacities 
MassFractions 
Metal Fractional Composition (default = S92) 

Note: metal abundances are renormalised 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 temperaturedensity mesh. The mesh can be specified by a range or a tabulation of {log_{10}(T) , log_{10}(ρ)} or {log_{10}(T) , log_{10}(R)} where T is the temperature in Kelvin, ρ the density in g cm^{3} and R=ρ/T_{6}^{3}, with T_{6}=T*1.E6. 
Please choose ONE of the following output options: 

An intermediate opacity file that can then be used locally for interpolation (temperaturedensity) with the code opfit.tar.gz.
