Abstract
The ENEAR project is an all-sky survey of nearby early-type galaxies. About 2200 new spectra and R-band images of over 1500 galaxies together with published data were assembled into a large catalog containing over 2000 objects with cz, sigma, photometric data, and line strengths on a uniform system. From this extensive database a magnitude-limited sample has been drawn comprising ~ 1400 galaxies brighter than mB = 14.5, cz < 7000 km/s, and type T -2 or less with measured distances (ENEARf) and about 500 early-type galaxies in 28 clusters/groups (ENEARc) to derive an internally consistent Dn-sigma relation to estimate galaxy distances. In this contribution we discuss some general properties of ENEAR and briefly describe some preliminary results.
