Abstract

This paper presents an algorithm for the optimal estimation of the centers of digitized stellar and semi-stellar images. If the image profile function is known, this an iterative, interpolative algorithm provides an optimal estimation of the image center. The algorithm converges rapidly and produces answers identical to those obtained from a X² -fit of the assumed profile function to the data.
