NED object is NGC 3448; Reference is 1979MNRAS.187..509R

   Figure 2. Right ascension-velocity plot constructed from the data of Fig. 1
 as described in the text, by including only signals which exceed 3{sigma}. The
 contour interval is uniform and the units are arbitrary. The HPFW resolution
 is 1.9 arcmin x 32 km per second. The hatched rectangles represent the optical
 positions and velocities of the labelled galaxies. Eight components are
 identified (C1-C8) for discussion purposes.
