\smallskip
$^a$ Radio pulsar ages are estimated as $P/(2\dot P)$,\\
     for RX J1856-3754 the age estimate comes from kinematical
     considerations (\citealt{wl02}).\\
$^b$ Distance to PSR 1055-52 is uncertain ($\sim$0.9--1.5~kpc)\\
$^c$ Total count rate (blackbody + non-thermal)\\
$^d$ Distances from parallactic measurements\\
$^e$ Distances from the dispersion measure\\
