[88.04] Velocity Fields for the Pair NGC 3379--NGC 3384

B. Tremblay, T. B. Williams, D. Merritt (Rutgers U.)

We have used the Rutgers Fabry-Perot (RFP) to observe planetary nebulae (PN) around the SB0 galaxy NGC 3384 and the E1 NGC 3379. We find that the rotation curve of NGC 3384 to be flat between about 2 kpc and 12 kpc, our last data point. We also measure a rotation curve for NGC 3379 that extends further than that of Franx et al. (1989) and appears to still be rising at our last data point at 5 kpc.
