Notes.

^(a)

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.

^(b)

FGCE 0745, satellite galaxy of NGC 2865. The radial velocity for this galaxy was taken from NED.
