Position‐velocity plot for IRAS 19254−7245. In this plot, the two‐dimensional velocity map has been collapsed in right ascension, yielding velocity as a function of declination. Two rotating disks can be seen, along with a kinematically distinct Hα plume in the southern galaxy. Note that where the two disks overlap, the velocities represent some average velocity of the distinct disk kinematics (see Fig. 6).
