Notes. Results of our 3D decomposition for each galactic component, where Hr1 and Hr2 are the disc characteristic scale lengths, χ2 and N the minimum chi-square estimate and the number of pixels used for each fitting, a2 and a3 the axial ratios of the second and third axis with respect to the major axis of the bar/bulge, n refers to the boxy (n = 4) or elliptical (n = 2) shape used for the fitting, Δα is the difference between the bar angle αbar and the bulge angle αbulge. Errors stand only for the fitting of the components separately through the minimization of its χ2. We clearly see some cases where the bar and the bulge are not aligned.
