Comparison of ALMA and SPHERE observations of MP Mus. Top left: Q_ϕ-image in H-band (λ_obs = 1.6 µm) taken with SPHERE/IRDIS. The colormap is shown in logarithmic stretch. The central blue circle masks the area covered by the coronagraph of the observation. Top right: comparison of the 1.3 mm continuum emission (orange contour), the SPHERE Q_ϕ H-band data (purple), and one of the ¹²CO (2−1) channels (blue). The 1.3 mm contour corresponds to the 5 RMS level, while only data above the corresponding 3 RMS levels are shown for the 12CO (2−1) and scattered light observations. Bottom: comparison of the radial profiles of the SPHERE Q_ϕ × r² in H-band (purple line), the 1.3 mm continuum (orange line), and the ¹²CO (2−1) emission (blue line). The SPHERE coronagraph is also shown.
