6 Conclusion

The first stage of commissioning and calibrating XMM-OM has been completed. The instrument is fulfilling its role of extending the spectral coverage of XMM-Newton into the ultraviolet and optical band, allowing routine observations of targets simultaneously with EPIC and RGS. Specifically, the instrument has successfully been demonstrated to provide wide field simultaneous imaging with the X-ray camera, simultaneous timing studies, and boresight information to arcsec accuracy. A number of results illustrating the scientific potential of XMM-OM are contained within this volume.

We would like to thank all the people who have contributed to the instrument; in its building, testing and operation in orbit, as well as those who have analysed the calibration data. The author list only contains a small fraction of those people involved. XMM-OM was built by a consortium led by the Principal Investigator, Prof. K. O. Mason, and comprising, in the UK, the Mullard Space Science Laboratory and Department of Physics and Astronomy, University College London; in the USA, University of California Santa Barbara, Los Alamos National Laboratory, & Sandia National Laboratory; and in Belgium, the Centre Spatial Liège & the University of Liège.
