Abstract:
    We present the global X-ray properties of the point source population
    in the grand-design spiral galaxy M101, as seen with XMM-Newton. 108
    X-ray sources are detected within the D25 ellipse of M101, of which
    ∼24 are estimated to be background galaxies. Multiwavelength
    cross-correlations show that 20 sources are coincident with H II
    regions and/or supernova remnants (SNRs), seven have
    identified/candidate background galaxy counterparts, six are
    coincident with foreground stars and one has a radio counterpart.

Description:
    M101 was observed with XMM-Newton for 42.8ks on 2002 June 4
    (Obs ID 0104260101). The EPIC MOS-1, MOS-2 and PN cameras were
    operated with medium filters in 'Prime Full Window' mode, which
    utilizes the full ∼30-arcmin field of view of XMM-Newton, covering the
    entire D25 ellipse of M101.
