r′-band cut from the field 16. In the image north is up and east is left. The red ellipses mark the objects which were classified as galaxies. The blue ellipse shows an object which was identified as a tidal feature. In the case of FDS16_LSB48, the object is not classified as a galaxy as it is asymmetric, has no clear center, and is connected to the nearby galaxy at its South-East side. The galaxies FDS16_LSB50 and FDS16_LSB85 appearing on the right are already identified in Bothun et al. (1991) as F2L7 and F2L8. Also several brighter galaxies appear in the image, but they do not match the surface brightness criteria of our sample. The image is shown in the same logarithmic scale used for the identification with lower and upper limits of −1 × 10^-12 ADU pix^-1 (or “–26.5” mag arcsec^-2) and 4 × 10^-11 ADU pix^-1 (or 22.5 mag arcsec^-2), respectively.
