J/A+AS/135/133 First DENIS I-band extragalactic catalog (Vauglin+ 1999) ================================================================================ First DENIS I-band extragalactic catalog Vauglin I., Paturel G., Borsenberger J., Fouque P., Epchtein N., Kimeswenger S., Tiphene D., Lanoix P., Di Nella-Courtois H.=1999A&AS..135..133V (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Galaxy catalogs ; Surveys ; Photometry, infrared ; Galaxies, IR Keywords: galaxies: general - catalogs - galaxies: photometry - surveys Description: REDCAT is the release of the provisional extragalactic catalogue constructed from the "Deep Near Infrared Southern Sky Survey" (DENIS). This catalogue contains 20260 galaxies with coordinates and I-band photometry (magnitude, diameter, axis ratio, position angle and a parameter related to the morphological type). In this new version photometric parameters are homogeneized to I-band measurements by Mathewson and Ford (1997, Cat. J/ApJS/107/97). Additional information on galaxies cross-identified with known objects can be obtained through the LEDA database at: http://www-obs.univ-lyon1.fr/leda/leda-consult.html This catalogue is the result of a tremendous work done along the chain Chile-Paris-Lyon. Many people are involved in this programm conducted by the P.I. N. Epchtein. We will not take the risk to mention them all. Their names will appear in forthcoming papers. The distribution on the sky is made of strips of 30 degrees in declination (180 frames per strip) south of +02{deg}. If you are satisfied with this catalogue, try to push the Community to support the DENIS project. Your suggestions are welcome for any improvement of this first release.
