Model datacube of a Bow Shock
Bow shock models for the system shown in Fig. 3
for two different orientations phi of the axis of the bow to the
line of sight. The large linewidths (white) and most
negative radial velocities (blue) occur near the apex in both cases, but
as the viewing angle decreases the bow appears wider and
the shift of the high radial velocity material from the apex of the
bow becomes more pronounced.
