Notes. The “single velocity component” shows the guesses and limits used in the one-velocity-component fit. The “first velocity component” and “second velocity component” show the guesses and limits used in the two-velocity-components fit. The FFP guesses represent the initial guesses used in the first fitting process for both one- and two-velocity-component fits. The final guesses are averaged of the parameters obtained from previous fits, used to improve the models in both one- and two-velocity-components fits. The Limits represent the range of values within which the returned parameters will lie.
