The project is operating since 2004 and with the support from the Spain-VO team they provide data access through a VO-SSAP and web services. Our goal here is to provide the same kind of service with the difference that the data is transformed and homogeneized in its flux units, to values in 'erg/(s.cm2)', and photon energy values in equivalent 'Hz' frequency values.
