Column desctription: (1) name; (2) radial velocity (cz) corrected for Local Group infall onto Virgo cluster [km s^-1]; emission line flux in units of 10^-15 erg s^-1 cm^-2: (3) H 4861, (4) [O III]5007, (5) [O I]6300, (6) H 6563, (7) [N II]6584, (8) sum of [S II]6716 and [S II]6731. The upper limit fluxes are measured at 3. The data below the horizontal line are from Ho et al. (1997). For these sources, values with uncertainties of 30%-50% are marked by `b', while highly uncertain values with probable errors of 100% are marked by `c'.
