Abstract:
Low-resolution objective-prism spectra (1360Å/mm at Hγ)
of 184 late-type stars in the Galactic antirotation direction
have been obtained with the Curtis Schmidt telescope at Cerro Tololo
Inter-American Observatory. The stars have been classified into three
groups: F6-G2, G3-K0, and K1-M8. Subsequent observations on the BV and
DDO systems have been obtained. The correlation between the thin-prism
classes and the DDO classes is as expected, with no significant
systematic differences of note. A comparison of Guide Star Catalog
magnitudes, corrected to V, is also made, with favorable results.
The stars in this list are expected to be useful for studying the
structure and star formation history of the Milky Way.
