Notes. Column 1: the name of the ISM tracer. Column 2: the best-fit model. “S” and “P” present the Sérsic and point component, respectively. Columns 3–4: source position – RA and Dec, respectively. Column 5: the Sérsic index of the ISM (the gas and the dust emission). Columns 6–7: the scale lengths along the major and minor axes, respectively. Column 8: the rotation angle defined in Appendix B. Columns 9–10: the half-light radii. The values in boldface are measurements near the kinematic major axes. Columns 11–12: the line flux for the point component and extended component, respectively. Columns 13–14: the dust continuum flux density for the point component and extended component, respectively. Column 15: the fraction of the nuclear component in the whole emission. Note that the errors of these parameters are all fitting-type errors. The complex correlated noise is not included. As claimed by the task reference of the CASA IMFIT, the correlated noise can bring 4% effect when 5σ detection of the emission for a 2D elliptical Gaussian fitting.
