Top part: for the three SNRs in the N19 complex (Sect. 4.5.2) we show a single CMD and SFH as they are in the same photometric grid of Harris & Zaritsky (2004). The three SNRs are shown on the same images, with from left to right (decreasing RA) : MCNR J0047−7309, J0047−7308, J0046−7308; the radio and X-ray spectra are shown in the same order. The radio contour levels are at 1, 3, and 8 mJy beam⁻¹. Bottom part: same as Fig. B.1 for MCSNR J0049−7314, with radio contour levels at 0.5, 1, and 2 mJy beam⁻¹.
