3-color surface photometry of a selected sample of early-type galaxies. I. Observations and data reduction.
This paper presents the results of two or three color surface photometry for a sample of 36 early-type galaxes obtained at the Canada France Hawaii Telescope with CCD cameras. We describe the calibration and data reduction procedures. A comparison of our results with previous work is made for NGC 3379. For each galaxy the B surface brightness profile along the major axis, as well as ellipticity and color profiles are displayed.
