The two best-fit model SEDs computed with hyperz. Left: the best-fitting model (χ² = 3.1) of an Im galaxy from the Coleman et al. (1980) template set; right: the Im galaxy template (χ² = 5.3) from the Bruzual & Charlot (1993) synthetic template set which also allows an age estimation of the stellar population, which in this case is 360 Myr. The corresponding extinction coefficient employed by the model is A_V  =  1.0^m. The x error bars correspond to the FWHM of the GALEX and SDSS bandpasses.
