Chandra (left panel, ObsID. 2735) and eROSITA (right panel, 1−2 Nov. 2019 observations) images of the field of view of 47 Tuc. Solid and dashed circles represent the source and background extraction regions for W2, respectively, for Chandra (red) and eROSITA (blue). The black circle encloses the inner region of the cluster excluded in the eROSITA analysis of Bao et al. (2023) and has a radius of 1.7′. The box in the bottom left corner is a close-up of the eROSITA source region as seen by Chandra, to show the X-ray sources that are blended with W2 in the eROSITA image.
