Notes.The position angle (PA°) in degrees and the ellipticity (e) were obtained from the B band image and applied to the remaining filters. The radius where the mean surface brightness is μB ≈ 26.5 mag arcsec-2 is the Holmberg radius, rH, and is given in arcseconds and kpc. The absolute B magnitude, MB, is calculated from the area inside rH and has been corrected for Galactic extinction (Schlegel et al. 1998). The MB errors are identical to the errors of the apparent B magnitude in Table 4.
