Percentage of galaxies in the DR2 sample with respect to the CALIFA MS distribution, as a function of the light-weighted axis ratio (b/a). Galaxies were separated into early-type galaxies (E+S0) and spiral galaxies (Sa and later). The CALIFA mother sample does not include any elliptical galaxies with b/a< 0.3. Error bars are computed from the binomial errors of the associated DR2 number counts.
