摘要：

We show that the D(n)-sigma relation, used for estimating distances to elliptical galaxies, needs a surface brightness correction. This correction follows from the universality of the R1/4 law, and can be derived analytically. It resolves the surface brightness bias problem of the D(n)-sigma relation noted earlier.
