Notes: Maximum Likelihood (ML) corresponding to probability P = 1 - exp(-ML) of existence; PSPC and HRI catalogue entries from Haberl & Pietsch (1999) and Sasaki et al. (2000a); R and Bfrom brightest USNO A2.0 object within 5 $^{\prime\prime}$ of X-ray position which provides a lower limit for the optical counterparts to the AGN candidates; delta denotes the angular distance between optical (USNO A2.0) and X-ray position for the cases with optical identification (HMXBs and foreground stars).
