Scientific paper

A catalog of identifications and positions for 3155 A, F, and G stars at the south Galactic pole is presented. The thin-prism spectra survey yields a set of uniformly selected A, F, and early G stars to a limiting magnitude of 16.0. Of 822 spectra classified with luminosities, 76 stars have classes III and IV-III; 21 stars are class IV, 669 stars are of luminosity classes V and V-IV, and 56 stars are classified as Vw for weak-lined or intermediate Population II objects. The mean spectral distribution for dwarf stars peaks at F9.3 V and declines sharply at G4. The mean color index for 1104 stars is a value typical of F9 V. Correlations between spectral types and photometry (b-y) index are also presented.
