Fig. 1

Top left: original galaxy image. Top middle: galaxy model derived from GASP2D fit considering a bulge, a bar, and a disk component. Top right: residual image derived from the subtraction of the galaxy model from the original image. Bottom left: ellipse-averaged SBD of the galaxy (black dots). Lines indicate the fit of the contribution of different components derived with GASP2D: dashed line for the bulge, dotted-dashed line for the bar, and the dotted line for the disk. The solid green line indicates the ellipse-averaged SBD of the best-fit model. Upper inset shows a zoom of the fit with a logarithmic scale for the distance to the center of the galaxy. Bottom middle: ellipticity radial profile measured from the ellipse fit on the galaxy image (black dots) and the best fit model image (green solid line). Bottom right: position angle (PA) radial profile measured from the ellipse fit on the galaxy image (black dots) and the best fit model image (green solid line).
