fit_
The double precision parameters fit_ define the initial value of the fit parameters. Depending on the fit format defined by fit_type, these values describe different purposes.
fit_1 represents the density
fit_2 represents the thermal width
fit_3 represents the shift along the parallel direction
fit_4 represents the kappa index.
The format is different from the actual physical format of these quantities. More details will follow later.
fit_ has to be defined for each fit of each species.
fit_ is part of the namelist &ffit_.
