reference of the comparison work (see description in the text); $N$: number of
galaxies in common; $\Delta I$: calculated offset between both studies (other
studies minus this work); $\sigma$: rms\ dispersion; $\sigma_{\rm exp}$:
expected rms\ from the errors; $t$: $t$-parameter of the comparison of
