Illustration of the flux integration perpendicular to the slit direction. The exponential profile is projected due to the inclination, i, of the disk (here i = 40°). Hence, the isocontours have elliptical shapes. The galaxy and slit dimensions shown here are typical of our data. In the upper part, the integrated and PSF-convolved profiles (solid line) are compared with an exponential function (dashed line).
