BVRI surface photometry of isolated spiral galaxies. Hernandez-Toledo H.M., Zendejas-Dominguez J., Avila-Reese V. <Astron. J., 134, 2286-2307 (2007)> =2007AJ....134.2286H

Total magnitudes and colors at various circular apertures, as well as some global structural/morphological parameters, are estimated. Morphology is reevaluated through optical and sharp-filtered R-band images, (B-I) color index maps, and archived near-IR JHK images from the Two Micron All Sky Survey. The CAS structural parameters (concentration, asymmetry, and clumpiness) were calculated from the images in each of the bands. Description: We have carried out an observational program at the Observatorio Astronomico Nacional at San Pedro Martir (OAN-SPM), Baja California, Mexico, devoted to obtaining uniform CCD photometric data for one of the most complete and homogeneous samples of isolated galaxies currently available, the CIG of Karachentseva (1973, Cat. VII/82). This sample amounts to more than 1050 galaxies in the northern hemisphere. The CCD BVRI images in the Johnson-Cousins system were obtained with a SITe1 detector attached to the 1.5 and 0.84m telescopes at OAN-SPM File Summary:
