UVEX is a double-pass survey in the RGO U, Sloan g, Sloan r and the He I 5875 filters. The aim is to find hot, blue, but relatively low luminosity objects in the Galactic Plane. As shown above, any Galactic population brighter than M_V = 10 shows a strong concentration towards the Galactic Plane. Single white dwarfs and white dwarf binaries (detached, AM CVn, Cataclysmic Variables, symbiotics), subdwarf B stars (including the ones in binaries) and extreme helium stars form the main target of the UVEX survey.

UVEX is performed using the INT Wide Field Camera, on the island of La Palma, and started in the Summer of 2006. It is a collaboration between scientists in the Netherlands, the United Kingdom and Spain. The UVEX pass bands are shown below.  The HeI 5875 filter band is 40 Angstroms wide and centered on the He I line at 5875 Angstroms.

The Galactic Plane is tiled in close to 7500 field centers and an equal number of offset fields and subdivided along the Galactic Plane constellations
(field locations can be found here).

NB: Note that all UVEX, IPHAS and VPHAS+ magnitudes are given in the Vega system, not AB!
