Removing Degeneracy of Microlensing Light Curves through Narrowband Photometry of Giants

“…We nd E(V{I) = 0.65. This result is in good agreement with the HST photometry of Baade's Window by Holtzman et al (1993){using the new abundance estimates by McWilliam & Rich (1994), as well as with the recent result from W UMa systems by Rucinski (1995). Next, we use as most reliable the direct temperature calibration of V{K photometry from lunar-occultation angular-diameters of eld giants by Ridgway et al (1980) and from Michelson interferometry by Di Benedetto & Rabbia (1987) and Mozurkewich et al (1991).…”
