Chimeras benchmark data set

<p>The Chimera data set is a benchmark for astronomical software working with multi-wavelength photometry of distant galaxies and quasars. The Chimera data set provides ground truth galaxy and AGN properties, and realistic broad-band photometry (Ultraviolet to Far-infrared). It is a benchmark for validating SED fitting codes that try to infer properties of the host galaxy with an active galactic nucleus or quasar.</p>
