Table 1: The best model fits to the MOS spectra of the source 52, and the MOS and PN spectra of PSR J0751+1807 and PSR J1012+5307. For PSR J0751+1807 the interstellar absorption ( $N_{\rm H}$ ) was fixed at $4 \times 10{\rm ^{20}}$ cm^-2. For PSR J1012+5307 the $N_{\rm H}$ was fixed at $7 \times 10{\rm ^{19}}$ cm^-2. For source 52, z was fixed at 0.255. All the errors shown are 1 $\sigma$ confidence limits. The fluxes and luminosities are given for the 0.2-10.0 keV band.
Table 2: Ephemeris of PSR J0751+1807 from the Nançay radio timing data.
Table 3: X-ray sources in the PSR J0751+1807 MOS field of view. Information includes the source identification number, right ascension and declination of the source, count rate and detection likelihood. The detection likelihood value is the value given by "emldetect'' for detection in the two MOS cameras, corrected for the coding error in versions 4.11.15 and earlier.
Table 4: Ephemeris of PSR J1012+5307 from the Effelsberg and the Lovell radio timing data. Errors on the last digits are shown in parenthesis after the values.
