Imagery of T Tau. (a) Moment 0 of the ¹²CO 2−1 line. (d) Moment 1 of the ¹²CO 2−1 line. (c) Same as (a) on a smaller scale. (d) Same as (b) on a smaller scale. (e) Integrated spectra of CO and SO₂ 14_0,14 − 13_1,13 from the region labeled I in (b). (f) Integrated spectra of SO₂ 14_0,14 − 13_1,13 from the region labeled II in (b). In each panel, red (or cyan) and black contours indicate the continuum and line emission as in Fig. 1. North is up, east is left.
