The molfit file, used by the myXCLASS function indicates the parameters of the species to be considered. Comments are marked with "%".
Example 1 (molfit file for myXCLASS function):
two molecules with one and three component. The first molecule is described by two core and one foreground component. (The source size definition for the foreground component is superfluous.) The second molecule requires one core component.
