Abstract

A two-color survey of nine fields of the first-epoch Palomar Sky Survey, centered on the North Galactic Pole, has been performed with the Minnesota Automated Plate Scanner. A set of neural network image classifiers are used to perform star-galaxy discrimination automatically to an imposed O magnitude limit of 20.0. We assess the efficiency of image classification and sample completeness through comparisons with a variety of independent studies of the NGP area.
