Top part: CMD, SFH, and radio-continuum spectrum of MCSNR J0041−7336 (first line), X-ray image with radio contours, optical image with X-ray contours, and X-ray spectrum (left, middle, and right panel of the second line, respectively). The radio flux density levels shown are at 0.1 mJy beam⁻¹, 0.5 mJy beam⁻¹, and 2 mJy beam⁻¹. Bottom part: same as above for MCSNR J048−7319, with same radio contour levels.
