Query: The Bar Pattern Speed in NGC 7079   We have used 2D Fabry-Perot absorption-line spectroscopy of the SB0 galaxy
NGC 7079 to measure its bar pattern speed, $\om$. As in all previous cases of
bar pattern speed measurements, we find a fast bar. We estimate that NGC 7079
has been undisturbed for at least the past Gyr or roughly 8 bar rotations, long
enough for the bar to have slowed down significantly through dynamical friction
if the disk is sub-maximal.
