Methods of Quantitative Objective Prism Spectroscopy Rose, James A. Abstract The methods employed to determine the spectral types and log g and Fe/H values for Galactic F-K stars in the vertical-structure investigation of Rose and Agustinho (1991) are described in detail. IIaO objective-prism plates obtained with the Curtis Schmidt telescope at CTIO using a 10-deg prism and a 135-A FWHM interference filter centered at 408 nm are digitized, and three spectral indices defined by Rose (1984) are measured and used to calculate the desired parameters. Results from tests of the accuracy of this method are presented, and it is shown that reliable separation of G dwarfs from G giants/subgiants is possible down to B = 13.
