ALMA and JVLA images on DM Tau. Left: previously published ALMA 225 GHz (~1.3 mm) continuum image (color and contours; Kudo et al. 2018; Hashimoto et al. 2021) smoothed to the synthesized beam of the JVLA image in the right panel. Dash-dotted and solid contours are 600 and 1200 µJy beam⁻¹, respectively. Right: JVLA 40–18 GHz (~7 mm) continuum image (color; θ_maj × θ_min=0″.074×0″.058, PA= −63°; RMS= 11 µJy beam⁻¹) in the region enclosed by the white box in the left panel. This image was created by jointly imaging all Q band observations listed in Table 1, limiting the wv-distance to >200 kλ. The images made with other combination of array configurations are provided in Fig. A.1. Contours are identical to those plotted in the left panel. The synthesized beams of the ALMA (black) and JVLA images (gray) are plotted in the bottom-left.
