Notes. The columns give the fitted parameters and reduced likelihood Lr. φ: bulge angle of the major axis with the Sun-Centre distance in degrees; x0, y0, z0: scale lengths along the 3 axes in kpc; normalization factor; Rc: cutoff radius in kpc, c∥ and c ⊥ : parameters of boxyness, Rd: disc scale length in kpc, Rh: disc hole scale length in kpc.
