Upper left panel: R-band acquisition image taken with FORS2 CCD1. The two brighter galaxies are IRAS 13197-1627 (MCG-3-34-64) on the left/east and MCG-3-34-63 on the top/north. The images are all oriented in the same way. Upper right panel: HST image obtained with the W606 filter of MCG-3-34-64. The position of XMMUJ132218.3-16424 is indicated by the Chandra error circle in red (the white circle was the XMM-Newton error circle) while the dashed green lines indicate the position of the slit during the FORS spectral observation. As stated in the text, the ULX candidate, once the astrometry is calibrated using USNO-B1 catalogs, falls within the Chandra error circle. The W606 magnitude of the target has been recorded to be m_F606 = 24.5. Lower panels: XMMUJ132218.3-16424 field as seen by XMM-Newton (left panel) and Chandra (right panel). In the XMM-Newton field the background extraction region for the pn is also displayed.
