The Sloan Digital Sky Survey Photometric System

Abstract

This paper describes the Sloan Digital Sky Survey photometric system, a new five-color (u‧ g‧ r‧ i‧ z‧) wide-band CCD system with wavelength coverage from 3000 to 11 000 Å. The zero points will be based on an updated version of the spectrophotometric AB<SUB>v</SUB> system. This updated calibration, designated as AB<SUB>95</SUB>, is presented in this paper.
