Images on DM Tau. Top-left: JVLA Q band image produced by jointly imaging all Q band observations listed in Table 1 (Q-all image; θ_maj × θ_min=0″.17×0″.12; PA=−53°; RMS=8.1 µJybeam⁻¹). Top-right: JVLA Q band image produced by jointly imaging all Q band, A array configuration observations listed in Table 1 (Q-A image; θ_maj × θ_min=0″.074×0″.058; PA=−63°; RMS=9.7 µJy beam⁻¹). Bottom-left: JVLA Q band image produced by jointly imaging all Q band, B, BnA, and A array configuration observations listed in Table 1 (Q-AB image; θ_maj × θ_min=0″.087×0″.062; PA=−61°; RMS=10 µJy beam⁻¹). Bottom-right: JVLA Q band image produced by jointly imaging all Q band, B and BnA array configuration observations listed in Table 1 (Q-B image; θ_maj × θ_min=0″.24×0″.16; PA=−54°; RMS=13 µJy beam⁻¹). Contours in all panels are the same as those presented in Figure 1.
