Notes. Column 1 reports the name of the LSB candidate, and in Cols. 2 and 3 we list the coordinates. In Cols. 4 and 5, the total r-band magnitude and the average g − r colour are reported. Columns 6 and 9 list the structural parameters derived from the 2D fit in the g band: the central surface brightness, the effective radius in kpc, the n exponent of the Sersic law, and the axial ratio, respectively. Magnitudes and colours are corrected for Galactic extinction using values from Schlegel et al. (1998).
