Small squares show the positions of X-ray photons detected by Chandra. They are color-coded according to the event energy. Black circles with a radius of 2″ mark the source-extraction regions for the two stars, centered on their optical locations at the time of the Chandra observation. The background image shows the 2MASS J-band image of the field (M. F. Skrutskie et al. 2006) from the 2MASS All-Sky Atlas Image Service (IPAC 2020).
