Table 3: Coincidences between the WeCAPP catalogue of variable stars and the X-ray selected catalogue of point sources by Kaaret (2002). A search radius of 1 was used. We give the identifier and WCS coordinates for the WeCAPP sources, and the identifier for the Kaaret (2002) sources. For sources coincident with the 2MASS catalogue Cutri et al. (2000), we give the 2MASS identifier also. We also show the difference r of the matching of both catalogues for each of the correlated sources.
