Spectral lines

The number of lines to be fitted decides how many lines follow in the parameter file: For each line a wavelength value (in units Å), a line width value ($\sigma$; units either Å or km/s; unit system for $\sigma$ is explained later), a weight factor for eventual auxiliary conditions (default 0), flags for the profile function (0: Gauss, 1: Lorentz), fitting $\lambda$ or $\sigma$, eventual lock of the line to the previous line, and a '' Beta'' value must be given. Therefore nlines must be followed by a list of nlines lines with start values of $\lambda_i$/$\sigma_i$, $f_i$ and flags $pro\_typ_i$, $FitLam_i$, $FitSig_i$, $LockLam_i$, and '' Beta'' in eight columns separated by blank or comma.
