Functions/Subroutines
subroutine, public	init_opal_table (tabledir, set_custom_tabledir)
	This subroutine is called when the FLD radiation module is initialised. The OPAL tables for different helium abundances are read and interpolated.

subroutine, public	set_opal_opacity (rho, temp, kappa)
	This subroutine calculates the opacity for a given temperature-density structure. Opacities are read from a table with given metalicity.

Variables
double precision, dimension(itmin:itmax, irmin:irmax), public	kappa_vals
	The opacity tables are read once and stored globally in Kappa_vals.

Detailed Description

This module reads in Rosseland-mean opacities from OPAL tables. Table opacity values are given in base 10 logarithm and are a function of mass density (R) and temperature (T), which are also both given in base 10 logarithm.
