The method of maximum likelihood is applied to the K dwarf tracer data and galactic-rotation constraint as presented by Kuijken and Gilmore (1989), using exactly the same assumptions and data. The maximum likelihood estimate of the column density of the galactic disk is 54 + or - 8 solar masses/sq pc, roughly 1 sigma higher than the KG estimate, 46 + or - 9 solar masses/sq pc. These results depend only very weakly on assumptions about the ellipticity of the halo.
