AXIS-SVO Data Centre

X-ray Medium Sensitivity Survey (XMS) sample

IFCA (as a member of the XMM-Newton Survey Science Centre, SSC) has led the elaboration of AXIS (An XMM International Survey) project, which constitutes the backbone of the XMM-Newton X-ray follow-up and identification (XID) programme performed by the SSC. The AXIS survey includes 36 fields observed by the XMM-Newton satellite. An optical follow-up focused on the medium flux sources has been done using different facilities. Using quality criteria, 25 fields have been selected from the AXIS sample to comprise the XMS (X-ray Medium Survey), a flux limited sample in several X-ray bands. It contains 319 unique X-ray sources, optically identified to a level above 90%. This resource comprises the optical spectra of these sources (Carrera F.J. et al. 2007, A&A, 469,27C; Barcons X. et al. 2007, A&A, 476,1191B)
