Cosmic X-ray background-subtraction attempt in the Centaurus cluster field. Left: Same as Fig. 2. Middle: Cosmic X-ray background-subtracted, fully corrected image (left minus right). The image was then adaptively smoothed with the same S/N as the left image. Right: Cosmic X-ray background map including the eROSITA Bubble emission in the 0.2 − 2.3 keV. We note that the color bar range of the right panel is different than the other panels.
