  High energy radiation from a planet host star can have strong influence on
the final habitability of a system through several mechanisms. In this context
we have constructed a catalogue containing the X-ray luminosities, as well as
basic stellar and planetary properties of all known stars hosting giant planets
(> 0.1 Mjup) that have been observed by the Chandra X-ray Observatory,
XMM-Newton and/or ROSAT. Specifically in this paper we present a first
application of this catalogue to search for a possible imprint of X-ray
photoevaporation of planet-forming discs on the present-day orbital
distribution of the observed giant planets. We found a suggestive void in the
semi-major axis, a, versus X-ray luminosity, Lx, plane, roughly located between
a ~ 0.05-1 au and Lx ~10^27-10^29 erg/s, which would be expected if
photoevaporation played a dominant role in the migration history of these
systems. However, due to the small observational sample size, the statistical
significance of this feature cannot be proven at this point.
