Description
We present deep near-IR photometry for Galactic bulge stars in Baade's Window, (l, b)=(1.0deg, -3.9deg), and another minor axis field at (l, b)=(0deg, -6deg). We combine our data with previously published photometry and construct a luminosity function over the range 5.5=<K0=<16.5, deeper than any previously published. The slope of this luminosity function and the magnitude of the tip of the first ascent giant branch are consistent with theoretical values derived from isochrones with appropriate age and metallicity. We use the relationship between [Fe/H] and the giant branch slope derived from near-IR observations of metal-rich globular clusters by Kuchinski et al. (1995AJ....109.1131K) to calculate the mean metallicity for several bulge fields along the minor axis.
