Modules
module	mod_cak_opacity
	This module reads in CAK line opacities in the Gayley (1995) notation (alpha, Qbar, Q0, kappae) from corresponding tables. Tabulated values assume LTE conditions and are a function of mass density (D) and temperature (T), which are both given in base 10 logarithm. The construction of the tables is outlined in Poniatowski+ (2021), A&A, 667.

Functions/Subroutines
subroutine, public	mod_cak_opacity::init_cak_table (tabledir)
	This routine is called when the FLD radiation module is initialised.
subroutine, public	mod_cak_opacity::set_cak_opacity (rho, temp, alpha_output, qbar_output, q0_output, kappae_output)
	This subroutine calculates the opacity for a given temperature-density structure. Opacities are read from a table with given metalicity.
subroutine	mod_cak_opacity::read_table (d, t, k, filename)
	This routine reads in 1-D (T,rho) values from a line opacity table and gives back as output the 1-D (T,rho) values and 2-D line opacity value.
subroutine	mod_cak_opacity::get_val_comb (k1_vals, k2_vals, k3_vals, k4_vals, logd_list, logt_list, d, t, k1, k2, k3, k4)
	This subroutine looks in the table for the four couples (T,rho) surrounding a given input T and rho.
subroutine	mod_cak_opacity::get_low_up_index (var_in, var_list, imin, imax, low_i, up_i)
	This subroutine finds the indices in rho and T arrays of the two values surrounding the input rho and T.
subroutine	mod_cak_opacity::interpolate_krt (low_r, up_r, low_t, up_t, logd_list, logt_list, kappa_vals, d, t, kappa_interp)
	This subroutine does a bilinear interpolation in the R,T-plane.
subroutine	mod_cak_opacity::interpolate1d (x1, x2, x, y1, y2, y)
	Interpolation in one dimension.
