Data for AX J194939+2631 available in the Virtual Observatory. The background image is a false colour composite made of r′ and i′ IPHAS images with Hα added to the red channel using the Lupton et al. (2004) algorithm. The ASCA positional uncertainty is shown as a green circle. A 30  ×  30 arcsec fragment of the error circle containing the IPHAS J194938.39+263149.2 source as seen in the near-infrared UKIDSS data is displayed in the bottom right inset. The Chandra X-ray source position is shown by an arrow, as well as the slit of the Calar Alto TWIN spectrograph (see Sect. 3.2).
