There is an issue with the initialization of the wavelengths of feature parameters. For the cube fitting, the wavelengths of the parameters whose values have been injected from previous results from a different spaxel will be initialized correctly. However, the wavelengths of those parameters that have not (i.e., are "new", meaning they have not been fitted in the spaxel that is used for injection) will have wavelengths that are at complete rest, contrary to the others, whose wavelengths account for the velocity gradient in the source (if the parameters were there from the beginning, in the first spaxel fitted, and through the chain of injections and fits).
