Optical Photometry

Optical photometry measures the apparent brightness of celestial objects in the optical region of the spectrum. The magnitudes and the colors of stars and galaxies allow to derive their physical properties and composition. This chapter presents the photometric systems used in optical astronomy and describes the techniques of securing photometric observations with CCDs. The observations are reduced by removing the effect of the atmosphere and by calibrating with constant brightness stars.
