-- We provide a new database of absorption and emission-line measurements based on the entire spectral atlas from the Sloan Digital Sky Survey (SDSS) 7th data release of galaxies.
-- 0.0 ‹ z ‹ 0.2
-- Foreground Galactic extinction is implicitly treated, whereas reddening in the SDSS galaxies is included in the form of a simple dust screen component affecting the entire spectrum that is accompanied by a second reddening component affecting only the ionised gas emission.
-- We provide a quality assessment for our fit to the SDSS spectra.
-- This quality assessment allows the identification of objects with either problematic data or peculiar features.





Figure : A typical example of SDSS galaxy spectrum(black solid line) and our fit(red). Dashed line is neat spectrum and the detected emission lines are shown at the bottom with violet. The inset panel shows entire wavelength range of the spectrum and the shaded region is marked.
