Abstract:
A preliminary list of 68.040 galaxies was built from extraction of
35.841 digitized images of the Palomar Sky Survey (Paper I,
1996A&A...311...12P 1996A&A...311...12P). For each galaxy, the basic parameters are
obtained: coordinates, diameter, axis ratio, total magnitude, position
angle. On this preliminary list, we apply severe selection rules to
get a catalog of 28.000 galaxies, well identified and well documented.
For each parameter, a comparison is made with standard measurements.
The accuracy of the raw photometric parameters is quite good despite
of the simplicity of the method. Without any local correction, the
standard error on the total magnitude is about 0.5 magnitude up to a
total magnitude of BT=17. Significant secondary effects are detected
concerning the magnitudes: distance to plate center effect and
air-mass effect.
The description of the construction of the catalog is given in Paturel
et al. 1996 and Garnier et al. 1996. Galaxies are detected on POS-I
and cross-identified with galaxies from the LEDA database
