Fig. 2


Hoinga SNR as seen in the eROSITA all-sky survey eRASS1. Photons to produce this 7. °5 × 47. °5 image were colour coded according to their energy (red for energies 0.2–0.7 keV, green for 0.7–1.2 keV, blue for 1.2–2.4 keV). An adaptive kernel smoothing algorithm was applied to the images in each energy band.
