Note: sources in bold face have a higher probability of membership on the basis of X-ray light curve and/or spectral analysis \citep[see][]{ScelsiXEST2006}.  
$^a$ Name of the X-ray source in the XEST catalog (the first 2~digits mark the field of the survey); $^b$ coordinates of the optical counterpart in the USNO catalog;
$^c$ equivalent on-axis count-rate for the PN in the $0.5{-}7.3$~keV band, averaged over the entire observation; 
$^d$ X-ray source variable according to the maximum likelihood algorithm described in \citet{StelzerXEST2006};
$^e$ magnitude in the $R$ band reported in the USNO catalog;
$^f$~infrared magnitudes reported in the 2MASS catalog; 
$^g$ quiescent count-rates (cts~ks$^{-1}$) for sources with strong flares: $180$~$\pm$ $40$ (\object{XEST-08-003}), $15.0$~$\pm$ $4.3$ (\object{XEST-27-084}).
