Optical and H I properties of the full LSB galactic sample. Panels represent distributions of (a) B-band central surface brightness with a bin of 0.2 mag arcsec−2, (b) B-band absolute magnitude with a bin of 0.2 mag, (c) B–V color with a bin of 0.05 mag, (d) central surface brightness against apparent magnitude in the B band, (e) the common logarithm of H I mass with a bin of 0.1 dex, (f) HI-line velocity width with a bin of 10 km s−1, (g) HI mass against B-band luminosity (measured by our own photometry), and (h) central surface brightness against H I mass.
