Abstract

The Compton Gamma-Ray Observatory has completed 4 years of observations comprising a full-sky survey and several deep pointings. The Crab is one of the strongest permanent sources in the CGRO energy range (20keV to 10GeV). Its total (pulsed and unpulsed) emission is often used as a calibration standard. We present the results of an analysis of data from all four CGRO instruments obtained during contemporaneous Crab observations made during Phase I, II and III between 1991 and 1994. Emphasis is given to the cross-calibration of the four CGRO instruments.
