Notes.
Systemic velocities deduced from our Hα line analysis. Heliocentric velocities given by the task rvidline from iraf. The errors for the velocities were estimated using Monte Carlo simulation for 100 runs, and they are about 40 km s-1 for all the spectra.
For the main galaxy, NGC 2865, the value for its radial velocity was taken from Smith et al. (2000).
