dc.description.abstract This project is using CCD images taken through different filters to determine the reliability of luminosity classifications based on objective-prism spectra. Kron-Cousins R and I filters are used in conjunction with an intermediate-band calcium hydride (CaH) filter to create a two-color plot. CaH-r vs. R-I diagrams. These are used to photometrically distinguish between red giants and dwarfs. The objective-prism plates from which this sample has been derived are currently being scanned to identify a much larger group of faint red stars. Accurate determinations of the luminosity classes for these sample stars would allow a more objective evaluation of the reliability of luminosity classes for stars detected in this larger survey.Photometric data taken at the National Undergraduate Research Observatory (NURO) and the Ball State University Observatory are combined in this study. Data gathered to date shows that the giant classification is much more reliable than the dwarf classification based on objective-prism spectral classification. Data collected to date will be reviewed in the context of the overall sample of faint red giant stars.
