Notes. The structural properties provided correspond to those found in this work. This table includes the name of the galaxies, their spatial location, their apparent magnitudes in the g and r bands, their central surface brightness, and their effective radii in arcsec. To the best of our knowledge the above galaxies were first found/discussed in the following references: (1) Abazajian et al. (2003), (2) Cohen et al. (2018), (3) Tanoglidis et al. (2021); object also known as SDSS J023939.36–081342.0, (4) Román et al. (in prep.); object also known as SDSS J024028.61–081436.7, (5) this work. The apparent magnitudes and surface brightness have been corrected by the following Galactic extinction: Ag = 0.095 and Ar = 0.065 mag. The quantities are given showing only the significant figures up to which the values can be regarded as reliable.
