Description
Studying three samples of early-type galaxies, which include
approximately 8800 galaxies and cover a relatively ample magnitude range
(<ΔM> ~ 5.5mag), we find that the coefficients as well as
the intrinsic dispersion of the Fundamental Plane depend on the width
and brightness of the magnitude range within which the galaxies are
distributed. We analyse this dependence, and the results show that it is
due to the fact that the distribution of galaxies in the space defined
by the variables depends on the luminosity.
