Scientific paper

We propose to obtain deep images of the field Sgr I, a low galactic latitude field at b=-2.6 degrees, to study the stellar population of the galactic bulge. Images will be taken in F439W, F555W, and F814W. The main goal will be to measure the luminosity function, and thus obtain the mass function, of the bulge stars. Understanding the IMF of the bulge, which samples older metal-rich stars, is critical to modelling galaxy evolution. With WFPC-2, we should be able to count stars down to a V of approximately 26.5, corresponding to an absolute magnitude of approximately 10. In addition to measuring the luminosity function, the multicolor data will be used to estimate the age and metallicity of the bulge stars. This data will complement data obtained with WFPC-1 in Baade's Window, a field at a galactic latitude of -3.9 degrees, but should also go significantly fainter. We will also obtain one far-UV image to look for the presence of strong UV emitting objects in the bulge population.
