Top and center panels: first-moment maps for C¹⁸O (top; v_lsr = 2.3–8.9 km s⁻¹) and ¹³CO (middle; v_lsr = 1.5–8.2 km s⁻¹). Beam size is (ellipses at lower left). Contours mark the continuum emission levels of 9.4, 15.1, 20.8, 26.5, 37.8, 49.2 mJy beam⁻¹, with a peak at 60.6 mJy beam⁻¹. The cross symbol marks the position of the star. Bottom panel: position-velocity diagram along major axis of projected disk in ¹³CO; position angle 134.3°. Yellow curves represent the Keplerian profiles for a 0.5 M_⊙ star.
