Notes. Column 1: Galaxy name. Column 2: Central luminosity from Mateo (1998). Column 3: LoS velocity dispersion of the stellar component as listed in Battaglia & Nipoti (2022). Column 4: Average number density of stars. Column 5: Typical age of the stellar population from Bettinelli et al. (2018, 2019), Aparicio et al. (2001), Carrera et al. (2002), de Boer et al. (2012, 2014), Mighell & Rich (1996), respectively. Column 6: Mean-free path of a star in the galaxy (maximum value of the semi-major axis for a binary system).
