ADC_Keywords: Galaxy catalogs ; Photometry, infrared Keywords: galaxies: general - catalogs 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) File Summary:

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.
