A new mapping of the velocity field of NGC 1275.

Velocities are presented for the extensive filamentary low-velocity system (V 5200 km s-1) in NOC 1275. Generally, the velocity gradients are small at all distances from the nucleus. For seven condensations in the filaments with radial distances from 38 to 122 (l = 485 pc at 100 Mpc), mean velocities range only from 5163 km 1 to 5293 km i Only in a few position angles are larger velocity gradients observed, with the velocity increasing to a maximum V = 5720 km 1 south of the nucleus. Tile generally small variation among filament velocities, galaxy velocity, and mean Perseus cluster velocity should place strict constraints on any model of filament formation. Velocities in the high-velocity system (V 8200 km s -1) NW of the nucleus are also presented. Tiley vary fairly smoothly from E to W, and are consistent with velocities in a rotating disk galaxy viewed close to edge-on, as discussed in an earlier paper.
