Abstract:
We present a catalog of near-infrared properties of LEDA galaxies,
using the full resolution images from the DENIS survey. The fluxes are
integrated in eight homothetic ellipses defined by their proper axis
ratio, position angle and major axis (up to twice the blue diameter at
the isophote 25mag/arcsec2) extracted from the LEDA database. From
the curves of growth in I, J and Kms photometric bands, we estimated
different apparent magnitudes and diameters ("total", "Kron" and
"isophotal"). Isophotal parameters refer to the limiting surface
brightnesses : 22.5(Imag)/arcsec2, 21.0(Jmag)/arcsec2 and
20.0(Kmsmag)/arcsec2 for the three photometric bands,
respectively. The result is a catalog of 753 153 objects (among
which there are 508 224 galaxies, 34 449 probable galaxies and 210 480
galaxies to be confirmed). The catalog gives about (the figures vary,
depending on the considered magnitude or diameter) : 668 000 I-band
magnitudes, 576 000 J-band magnitudes, 357 000 Kms-band magnitudes
and 452 000 I-band diameters, 299 000 J-band diameters, 114 000
Kms-band diameters.
The typical standard deviations for I, J and Kms magnitudes are
0.14, 0.15 and 0.25, respectively, for magnitudes limited at I=16,
J=15 and Kms=14. The contamination by superimposed objects
probably remains the major source of problems and could require future
improvement. The completeness limits in magnitude are about : 15.5,
14.5 and 13 in I, J and Kms, respectively.
Description:
The catalog is sorted according to the field 1 (right ascension and
declination for 2000).
There are 753153 lines of 359 characters each.
Unknown values are either 0.00 (or 9.99 if 0.00 is allowed)

Note (1): Names that correspond to a multiple system are written in parenthesis.
Names that do not agree with NED identification have been written with
a question mark (?). Names that have been moved from one galaxy to
another since the first PGC (1989A&AS...80..299) catalog have been
written with an exclamation point (!).
Note (2): Object nature is:
G = confirmed galaxies
g = possible galaxies
? = object to be confirmed
Note (3): Parameter G to characterize the nature of the object for not
confirmed galaxies. The higher the parameter, the more secure the
acceptation as galaxy.
G = -2.5log(fmaxi) + 2.5log(Scentral),
where fmaxi is the central peak flux (calibrated and corrected for
extinction) and Scentral is the surface area of the central region.
Note (4): Flags of quality:
Each flag has a value 0 when there is no problem or 1 when one can
suspect the data to be affected. The flags characterize the following
features (in this order from the left to the right) :
- flag 1 for quality of zero point,
- flag 2 for quality of the night,
- flag 3 for quality of the position of the object within the frame
(edge effect),
- flag 4 for superimposed sources.
