3.2 Diameters
µ = 27.68 + 5[log D(n) - log D(0)], where D(0) is the ``face-on'' diameter (in minutes of arc) in the standard system of the Reference Catalogue and log D(n) = 0 - 0.10n (D in kpc, n 5), with
0 = 1.10 | 1.15 | 1.20 | 1.25 | 1.30 | 1.35 | 1.30 | 1.20 |
T = E | L | S0,1 | S2,3 | S4,5 | S6,7 | S8,9 | I9. |
