Summary of Programme

We propose multi-colour optical imaging of approximately 200 fields drawn from the XMM-Newton observing programme in order to provide the optical data needed to realise the full potential of the XMM-Newton Serendipitous X-ray Sky Survey. The INT data, combined with the XMM-Newton X-ray data, will provide an X-ray/ optical catalogue of ~10000 - 20000 sources over 25 sq deg of the sky which will represent an unequaled resource for a range of front-line areas of astrophysics.
