| Popis: | The EFAR project is a long-term study of 736 candidate early-type galaxies in 84 clusters lying in two directions towards Hercules-Corona Borealis and PerseusPisces-Cetus at distances 6000–15000 km/s. In the following we discuss the goals of the project and the properties of the photometric and spectroscopic database. We present a new method, based on maximum likelihood, to determine the parameters of the Fundamental Plane and describe the distribution of galaxies in it. The algorithm takes into account the effects of errors and selection and is superior to least-squares procedures. |
