The Galactic Plane Survey:
This survey led by Christian Motch, is based on 26 XMM-Newton observations, obtained at | b | < 20°,
distributed over a large range in Galactic longitudes and covering a
summed area of 4 deg2. The flux limit of this survey is 2
x 10-15 erg cm-2 s-1 in the soft
(0.5-2 keV) band and 1 x 10-14 erg cm-2 s-1 in the hard (2-12 keV) band. A total of 1319
individual X-ray sources are detected. Using optical follow-up observations
supplemented by cross-correlation with a large range of multi-wavelength
archival catalogues we 316 X-ray sources have been identified, see Nebot Gómez-Morán (2013).
