Columns are as follows: (1) Source name; (2) XMM-Newton Observation number; (3) Right Ascension and Declination (J2000) of the source (X-ray position); (4) Angular distance (in arcmin) between the source and the MOS2 image center; (5) Source count rate, and $1\sigma$ error, in the 4.5-7.5 keV energy band (units of 10-3 cts/s). In Table 1 we have reported the MOS2 conversion factors between the 4.5-7.5 keV count rate and the flux as a function of the energy spectral index, the hardness ratio HR2 and the blocking filter; (6) and (7) Hardness ratios computed as described in Sect. 3.3. The errors on the hardness ratios have been evaluated using simulations and correspond to $1\sigma$; (8) Optical spectroscopic classification (AGN1: broad line AGN; AGN2: narrow line AGN; GAL: Optically Normal Galaxy; CL: Cluster of Galaxies; BL: BL Lac Object; star: star; ?: Tentative classification; see Sect. 3.2 for details).

NOTE - a These 11 sources belong to the HBSS sample but not to the BSS sample, while the remaining 56 HBSS sources are present also in the BSS sample.

b A detailed X-ray and optical spectral analysis of these sources have been reported in Caccianiga et al. (2004).

c These sources are more extended than the XMM-Newton EPIC MOS2 Point Spread Function at their off-axis angle. Count rates have been evaluated using aperture photometry.

d A detailed X-ray and optical spectral analysis of these sources have been reported in Severgnini et al. (2003).

e A detailed X-ray spectral analysis of these sources have been reported in Galbiati et al. (2004).
