Left: Gas particles in the best model representing the NGC 7714 H I loop or tail (feature 2 of Paper I) at time ﹩t=120﹩ Myr, as well as a few representative contours to mark the location of the galaxy disks. Right: The same gas particles, at a time (﹩t=0.0﹩ Myr) just before closest approach, and the sample disk contours. At times between those of the two panels the companion moves clockwise from the right to the left and a bit below the primary.
