GALEX ﹩\mathrm{FUV}\,-\mathrm{NUV}\,﹩ color plotted against the UV slope β estimated from GALEX spectra. Our sample is represented as follows: Open squares are normal galaxies, and filled squares are Seyfert 2 galaxies. We use larger squares for galaxies with ﹩z< 0.1﹩. There is no clear relationship between β and ﹩\mathrm{FUV}\,-\mathrm{NUV}\,﹩ for the whole galaxy sample. However, there is a tight relationship if we use only galaxies at ﹩z< 0.1﹩. Within the GALEX maximal 0.1–0.15 uncertainty, all the lowest redshift galaxies closely follow the law (solid line) given by Kong et al. (2004) and the Kinney et al. (1993) templates (crosses) integrated into GALEX bandpasses.
