Scientific paper

We used all the SDSS DR7 spectroscopic sample as the starting base. Then, the selection of objects was based on Sanchez Almeida et al. (2010ApJ...714..487A) who performed an unsupervised automated classification of all the SDSS spectra. Basically, we chose galaxies with redshift below 0.25, and with good photometric data and clean spectra, meaning objects not too close to the edges, not saturated, or not properly deblended. The final catalog contains 698420 objects for which we estimate the morphology (also available at http://gepicom04.obspm.fr/sdssmorphology/Morphology2010.html ).
(3 data files).
