Characterisation of AGN from the XMM-Newton Slew Survey

This paper is based on service observations made with the WHT operated on the island of La Palma by the Isaac Newton Group in the Spanish Observatorio del Roque de los Muchachos of the Instituto de Astrofísica de Canarias. We are grateful to the ING support astronomers O. Vaduvescu and L. Dominguez and WHT observer M. Cappellari for carrying out these service observations. The Swift BAT result was obtained with thanks to H. Krimm.
