Abstract
We present deep wide field (16 ′ .4×16 ′ .4 ) Washington CT1 CCD surface photometry of the giant elliptical galaxy NGC 4472, the brightest member in the Virgo cluster. Our data cover a wider field than any previous CCD photometry as well as going deeper. Surface brightness profiles of NGC 4472 are not well fit by a single King model, but they can be fit approximately by two King models: with separate models for the inner and outer regions. Surface brightness profiles for the outer region can also be fit approximately by a deVaucouleurs law. There is clearly a negative color gradient within 3 ′ of NGC 4472, in the sense that the color gets bluer with increasing radius. The slope of the color gradient for this region is derived to be �µ(C T1)
