This data server provides access to the ARCHES Spectral Energy Distributions (SEDs).
The objective of ARCHES is to build scientifically-validated spectral distributions for the stars, galaxies and clusters of galaxies detected by the ESA X-ray space observatory XMM-Newton and included in the 3XMM catalogue. These multi-wavelength enhanced data sets will open new avenues of investigation. In order to ensure the largest audience, the ARCHES SEDs are distributed to the international community through the Virtual Observatory.
This archive has been developed in the framework of the ARCHES project (7th Framework of the European Union nº 313146). The system is maintained by the Data Archive Unit of the Centro de Astrobiología
