Left: detail of IRAC [3.6 μ] image. Right: same area as seen by GALACTICNUCLEUS K_S band. This image illustrates the considerable difference in angular resolution between the main surveys used in this work. The dark rings present in GALACTICNUCLEUS brightest stars (also seen in Figs. 5 and 6) are a consequence of a combined effect of the holographic data reduction technique and the image scaling. These stars are not marked or outlined in any way.
