\begin{table}%t1
\caption{List of all candidate members. "XEST id'' refers to the name of
the X-ray source in the XEST~catalogue \citep[][ the first 2~digits mark the
field of the survey]{GuedelXEST2006}. RA~X and Dec~X are the coordinates of the
X-ray source (corrected for boresight shift). CR is the equivalent on-axis
count-rate for the PN in the $0.5{-}7.3$~keV band, averaged over the entire 
observation (see notes for the quiescent level of the sources with strong 
flares). $L_{\rm X}$ is estimated in
the $0.3{-}10$~keV band from CR (see text), except where noted. A~"y'' in the
column~"var'' means that the X-ray source was found to be variable according to
the maximum likelihood algorithm described in Sect.~\ref{lc_sp}. The 
7${\rm th}$~column is the designation of the infrared counterpart in the 2MASS~catalogue; "offset'' is the distance between the positions of the X-ray source
and its IR~counterpart; $J$, $H$ and~$K_{\rm s}$ are the infrared magnitudes
reported in the 2MASS~catalogue. Sources in bold face are the most probable
candidates on the basis of light curve and/or spectral analysis 
(Sect.~\ref{lc_sp}).}\label{tab:lista}
