Abstract
We present preliminary results of multicolor broadband CCD (BVRI) photometry for a sample of 230 isolated (elliptical and spiral) galaxies drawn from the Catalog of Isolated Galaxies (CIG) by Karachentseva (1973). Images were acquired at the San Pedro Mártir (OAN-SPM) National Optical Observatory in Baja California, Mexico. We estimated total magnitudes and colors at various circular apertures, as well as global structural/morphological parameters: Concentration, Asymmetry and Clumpiness (CAS).
