The Chandra/HRC-I (0.1–10 keV) image of the ESO 243-49 HLX-1 field taken on UT 2009 July 4, where yellowsmall circle corresponds to the location of ESO 243-49 HLX-1 and white arrow points correspond to 2XMM J011050.4-460013 source. The large circles (labeled nominal and offset) show the two pointing positions used for the light curve and spectrum extractions in order to minimize contamination of ESO 243–49 HLX–1 by nearby source.
