LFs for different types of galaxies in different environments. The upper LFs in each panel are the observed LFs that are shifted up two units in logarithmic scale and right by one mag. The lower LFs in each panel are the attenuation-corrected LFs. For elliptical galaxies (bottom panel), only the observed LFs are shown. Dotted lines stand for the least dense (void) environments; red solid lines stand for the most dense (supercluster) environments. The filled areas show the 95% confidence regions of the LFs.
