Galaxy photometry. I. Techniques
Abstract
Techniques for the derivation of nuclear magnitudes in galaxies are summarized. A new method for rapid estimation of nuclear magnitudes by iris photometry is presented and evaluated. It is concluded that with proper calibration, nuclear magnitudes for galaxies in clusters may be estimated with an uncertainty of about j 0.1 mag.
