Notes. Values of the kinematic parameters used as initial values and bounds during the fitting process. The two-BELs component refers to the components used in model-2 and model-4, and the bf-vel is the velocity shift value of the BELs component obtained from the first best fit with model-1 (see Sect. 3). For BHO-cont and AGN-cont values are for pPXF mathematical problem and solution and do not affect the profile of the templates.
