Fig. A.2
Position-velocity diagram of the CN emission along the disk’s major axis. The dashed curve is a Keplerian velocity profile for a stellar mass of 0.61 M⊙ at an inclination of 87° and a systemic velocity of 3.70 km s−1 LSRK. Labels A, B, C, D, and E indicate the five observed HF transitions (see Table 3).
