Description:
This catalog presents homogeneous photometric parameters of 791
northern bright galaxies based on surface photometry. The observations
were made with the 105 Schmidt telescope at Kiso Observatory in the
photographic V band, mostly during 1984-1988. This catalog is the
first machine-readable version of Part II of the "Photometric Atlas of
Northern Bright Galaxies" (Kodaira et al. 1990). The fields in the
catalog include galaxy name, position (B1950), morphological type,
radial velocity, galactic V-band absorption, effective radius,
apparent magnitude, and parameters of the ellipse fitted to the
photometric galaxy image.
Abstract :
Galaxies are the most massive, luminous astronomical objects bound by
self gravity and comprise the major fraction of luminous mass in the
universe. Recent investigations of galaxies often require statistical
analysis of a large body of observational data. High degree of
homogeneity of the data is the key point to the success of such
investigations.
This catalog presents homogeneous photometric parameters of 791
northern bright galaxies on the basis of modern photographic surface
photometry. Sample galaxies are taken from the Revised Shapley-Ames
Catalog of Bright Galaxies (Sandage and Tammann 1981) and most of them
are members of the Local Super-cluster.
Observations were made with the 105cm Schmidt telescope at the Kiso
Observatory, Institute of Astronomy, University of Tokyo, in the
photographic V band (Kodak IIa-D emulsion combined with a Schott GG
495 filter) mostly during 1984-1988. Sample galaxies photographed on a
total of 280 Schmidt plates were scanned with the PDS 2020 GMS
microdensitometer at the Kiso Observatory during April-August 1988.
Data reduction for standard surface photometry was carried out using a
software library SPIRAL (Ichikawa et al. 1987; Okamura 1988) during
July-September 1988. The intensive plate measurement and data
reduction secure high homogeneity of the present data.
This catalog is the first machine-readable version (Ver.1) of Part II
(The Catalog) of the 'Photometric Atlas of Northern Bright Galaxies'
(Kodaira et al. 1990), which also includes in Part III illustrative
information such as images, isophotal maps, luminosity profiles, and
ellipses fitted to the isophotes. Image data of sample galaxies can be
obtained in FITS format magnetic tapes upon request, and it is planned
to distribute them on CD-ROMs.
We request that those errors in this catalog that are found by the
user be transmitted to S. Ichikawa, National Astronomical Observatory,
Mitaka, Tokyo 181 Japan (e-mail : ) so that
they can be corrected in future versions.
