摘要
We present in this paper an exhaustive compilation of all published data of extragalactic Cepheids. We have checked every light curve in order to characterize the different types of Cepheid and detect potential overtone pulsators, or to estimate the quality of the data. This compilation of about 3000 photometric measurements will constitute a very useful tool for astronomers involved for instance in the extragalactic distance scale.

Updated version of this database is now available through WWW at http://www-obs.univ-lyon1.fr/~planoix/ECD/ . 1321 Cepheids located in 39 galaxies make up the base at the moment. One can also plot PL-relations and compute distance moduli based on Hipparcos PL-relations
