Notes.  The sign (f) after a value means that the value was fixed during the fitting procedure. The sign (b) means that the parameter value was bound to the value of the corresponding parameter of the previous model component. The sign ``-'' means that the model component is not included in the total model, while dots in the right column only mean that there are more values related to the individual spectra which are not necessary to be all shown in the table.
