Query: A Near-Infrared Photometric Survey of Metal-Poor Inner Spheroid Globular
  Clusters and Nearby Bulge Fields   Images recorded through J, H, K, 2.2 micron continuum and CO filters have
been obtained of a sample of metal-poor ([Fe/H] < -1.3) globular clusters in
the inner spheroid of the Galaxy. The shape and color of the upper giant branch
on the (K, J-K) CMD, combined with the K brightness of the RGB-tip, are used to
estimate the metallicity, reddening, and distance of each cluster. CO indices
are used to identify bulge stars, which will bias metallicity and distance
estimates if not removed from the data. Bulge fields were also observed near
each cluster. The slope of the bulge giant branch luminosity function does not
vary between most fields, although the LFs in Baade's Window and near NGC 6273
are significantly shallower than average. The data also suggest that the HB
content may not be uniform throughout the bulge, in the sense that a larger
than average number of red HB stars may occur in fields closest to the Galactic
Center.
