This list was last updated on August 22, 1999. Col. 1: Galaxy name; M31 is also known as the Andromeda Galaxy; NGC 4594 is also known as the Sombrero Galaxy. Col. 2, 3: Right ascension and declination (epoch 2000). Col. 4: Constellation. Col. 5: Morphological type (de Vaucouleurs & Pence 1978; RC3). Col. 6: Distance (see Kormendy & Richstone 1995). Values are based on a large-scale, flow field solution, an assumed Virgo Cluster distance of 15.3 Mpc = 50 million light years, and a Hubble constant of H_0 = 80 km/s/Mpc. BH mass scales as D; %_BH is independent of D. Demographic conclusions are not sensitive to the distance scale. Col. 7: B-band bulge absolute magnitude, based mostly on B_T in RC3. Exceptions are M 31 (V_T = 3.28 from Kent 1987b), NGC 3115 (B_T = 9.75 from Capaccioli et al. 1987), NGC 4594 (B_T = 8.65 from Burkhead 1986), and the Galaxy (M_B adapted from Kent et al. 1991). Galactic absorptions are taken from Burstein & Heiles (1984). Assumed bulge-to-total luminosity ratios are: M 31: B/T = 0.24 (de Vaucouleurs 1958), NGC 3115: 0.94 (Capaccioli et al. 1987), NGC 4594: 0.93 (Burkhead 1986), NGC 4258: 0.063 (approximate value near the bottom of the distribution of B/T values for Sbc galaxies, see Simien & de Vaucouleurs 1986). NGC 1068, NGC 4945: 0.1, 0.02 (derived similarly). Col. 8: Black hole mass for the best-fitting isotropic dynamical model. Col. 9: Ratio of black hole mass to the mass of the bulge component expressed as a percent. Bulge masses are determined from M_B,bulge and from M/L ratios measured in the black hole papers. For NGC 4258, M/L_r = 4.08 is from Kent (1987a); this disk value is probably a good approximation for the bulge-like component as well. Col. 10: Discovery papers.
