Fit model

Fit model consist from the number of the parameters to construct the profile of absorption systems. These parameters (corresponding to multicomponent Voigt profiles and additional ones) can be set within the Fit model widget

Fit model widget

The left-hand side of the panel allow one to set-up multicomponent Voigt profile parameters throught the Tab menu. The right-hand side supply the adidtional parameters (e.g. continuum, resolution, isotopic ratio etc).

Multicomponent Voigt parameters:

Usually one need to add the species to fit by using the add species field in the bottom left-hand part of the widget. The species will appear in the Tab above. Than you can add/duplicate/delete additional component using the buttons at the bottom.
