Fig. A.1


Details of the model for the HVC shown in Fig. 10 with light-blue curves; note that higher velocities correspond to lower distances to the far-IR exciting source in a decelerating field. a) Column density of H nuclei (assuming XOH = 2.5 × 10-6) in intervals of 100 km s-1 as a function of the radial velocity for Rout/Rint = 1.3, NOH = 1.6 × 1017 cm-2, vint = 1700 km s-1, and vout = 100 km s-1. b) Rotational temperature of the Π3/2 J = 7/2 level (the lower level of the OH65 transition) relative to the ground state, as a function of the radial velocity. c) OH84 and OH65 optical depths along a ray passing through the center, and d) covering factor of the continuum, both as a function of the line-of-sight velocity. At low projected velocities (<400 km s-1), the covering factor exceeds unity, which generates reemission from the limb of the outflow.
