Notes. Column 2: K band absolute magnitude of bulges. Column 3: Effective radius of bulges. Column 4: Stellar mass estimated in K band using M/L = 0.6 (McGaugh & Schombert 2014). Columns 5 and 6: Mass of central black holes using M• and K band luminosity. Columns 7–9: Mass of central black holes using the M• − σ relation. Columns 10–12: Mass of central black holes using the M•–Mass of bulge relation.
