VII/234 DENIS catalog of galaxies (Paturel+, 2003) ================================================================================ The provisional DENIS I-band catalog of galaxies revisited.

Galaxies not cross-identified with already known galaxies have been visually controlled using the DSS1 images and, occasionally, the coordinates were remeasured. The typical accuracy of coordinates is about 2". The typical error on I-band magnitude is about 0.2mag. The final catalog gives the most common names, the J2000 coordinates, the I-band magnitude, the diameter, the axis ratio and the position angle for about 43000 galaxies. It covers roughly 67% of the southern hemisphere. It is homogeneously sampled up to I=14.5 mag. The data are also available via the LEDA database.

Note (2): The zero-point of these magnitude is adjusted to the Mathewson system (Mathewson et al., 1992ApJS...81..413M) The standard deviation is about 0.2 mag. Note (3): This diameter is converted to the Mathewson system (1992ApJS...81..413M) at the isophote 23 I-mag/arcsec^2^, using linear log-log conversion. Note (4): Its value covers the range 0-180{deg}. A few values exactly equal to zero are taken as 180{deg} -------------------------------------------------------------------------------- Acknowledgements: Georges Paturel ================================================================================ (End) Patrica Bauer [CDS] 07-Jan-2003
