Notes. The GALFIT results for the coordinate of the centre of the galaxy, the Sersic index (n), axis ratio (b/a), position angle (PA), and effective radius (Reff). The V-band magnitude is estimated adopting the transformation equation provided by Jester et al. (2005). The physical parameters are calculated by adopting a distance modulus of 27.84 ± 0.02 mag (Jacobs et al. 2009) for NGC 253.
