Abstract:
    This is the first in a series of papers in which we analyze
    medium-resolution spectra of over 400 K and M giants in Baade's
    Window. Our sample was selected from the proper motion study of
    Spaenhauer et al. (1992AJ....103..297S). We have measured
    radial velocities for most of the sample, as well as line-strength
    indices on the system of Faber et al. (1985ApJS...57..711F). We
    analyze the random and systematic errors in velocities and line
    strengths, and show that the bright (V<16.0) stars in our sample are
    predominantly foreground disk stars along the line of sight toward
    Baade's Window. We find that most of the bulge K giants have stronger
    Mg absorption at a given color than do stars in the solar
    neighborhood. If the K giants in our sample are moderately old, we
    suggest that on average they may have [Mg/Fe] approximately +0.3,
    consistent with the results of recent high-resolution spectroscopy in
    Baade's Window.

Note (1): Radial velocity measured by Rich (1990ApJ...362..604R). Rich's
          spectra were taken either at "low" resolution (4.5A; similar to 
	  the author's AAT and CTIO spectra) or "high" resolution (2.7A). 
	  Rich estimates velocity errors of 34km/s (L) and 15km/s (H) for 
	  the two samples.
