Top: Examples of the vertical profiles of UGC 10111 extracted parallel to its minor axis. Both lines show profiles taken along two vertical cuts closest to the galactic center (see isophotal map in the bottom panel). The 10^{﹩\arcsec﹩} bar indicates the level of ﹩\mathrm{S}\,/ \mathrm{N}\,=3﹩. Middle: Radial profiles extracted along the major axis (dashed line) and parallel to it (solid lines). The latter were used to derive the structural parameters of the galaxy. Upper and lower lines are shifted from their real positions by +2 and −2 mag arcsec⁻², respectively. They are extracted along the upper and lower radial cuts shown on the isophotal map. The 10^{﹩\arcsec﹩} bar indicates the level of ﹩\mathrm{S}\,/ \mathrm{N}\,=3﹩. Bottom: Isophotal map of UGC 10111. The isophotes correspond to 20.5, 21, 21.5, 22, 22.5, 23, 23.5, 24, 24.5, 25, and 25.5 mag arcsec⁻² in the R band. The places where the profiles were extracted are shown by lines. All artifacts and stars that could be seen in the picture were cleaned out manually before the structural parameters were found.
