Fig. 2
Source regions filtered for soft X-ray emission (0.2 − 2.0 keV). The target positions are marked by circles with a 2′′/15′′ radius in the Chandra/XMM-Newton observations; the position of known companions is marked by crosses. In the panel of WASP-80, a nearby detected 2MASS source is also marked by a cross. The X-ray source close to HAT-P-2 is discussed in Sect. 3.1. Six out of seven targets have been detected as X-ray sources.
