Abstract:
A release of multicolor broadband (BVRI) photometry for a subsample of
44 isolated spirals drawn from the Catalogue of Isolated Galaxies is
presented. 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
