Combined X-ray image of eROSITA observations in the field of 47 Tuc with a total radius of 420. We studied all visible point-like sources (888 sources). The half-mass radius of 47 Tuc is shown within the solid white region. The dashed red circles show the regions observed by five eROSITA observations. The larger and smaller solid green regions with radii of 18:08 and 1:07 show the area that is covered by all observations and the extent of the unresolved emission from the centre of 47 Tuc, respectively. The area between these two regions was used to calculate the X-ray luminosity function (see Sect. 5.5).
