Velocity fields of five inversion transitions of NH₃ as well as the CH₃OH line, as measured in absorption toward the HC HII region W51e2-W with the JVLA B-array. The total intensity 0th moment maps (contours) are overlaid on the velocity field 1st moment maps (images). Colors indicate V_LSR in km s^-1. The images were constructed with a 004 pixel for all transitions. The contours represent factors 1, 2, 4, 6,.... of −50 mJy beam^-1 km s^-1, for all transitions. A flux cutoff of −5 mJy beam^-1 (~3σ) was used to create 1st moment maps for the (6, 6), (7, 7), and (9, 9) transitions, and a slightly higher cutoff of –7 mJy beam^-1 for the (10, 10) and (13, 13) transitions. We note that while the lower excitation transitions (6, 6) and (7, 7) show an apparent velocity gradient along NE-SW, higher excitation lines consistently show a gradient along E-W. We ascribe this difference to a weaker component with blueshifted velocity detected toward SW in the lower excitation lines. The synthesized beams (019–026) are shown in the bottom left corner of each panel (see Table 1).
