DAOPHOT — Stellar Photometry Package

Version 1.2

Introduction


Abstract

DAOPHOT is a stellar photometry package designed by Peter Stetson at DAO to deal with crowded fields. The package performs various tasks including finding objects, aperture photometry, obtaining the point-spread function, and profile-fitting photometry. Profile fitting in crowded regions is performed iteratively, which improves the accuracy of the photometry.
