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.

1- 24 A24 ---- DENIS Provisional DENIS identifier
26- 34 A9 --- PGC PGC (Cat. VII/119 number (for retrieving
a galaxy in the LEDA database)
36- 49 A14 --- Name Alternate name (according to LEDA)
51- 52 I2 h RAh Right ascension (2000.0)
53- 54 I2 min RAm Right ascension (2000.0)
55- 58 F4.1 s RAs Right ascension (2000.0)
59 A1 --- DE- Declination sign
60- 61 I2 deg DEd Declination (2000.0)
62- 63 I2 arcmin DEm Declination (2000.0)
64- 65 I2 arcsec DEs Declination (2000.0)
67- 71 F5.2 mag Imag I-band total magnitude
73- 77 F5.3 [0.1arcmin] logD log10 of apparent diameter
79- 83 F5.3 --- log(a/b) log10 of axis ratio (major/minor axis)
85- 89 F5.1 deg PA Position angle (from North towards East)
91- 94 F4.1 --- MType Parameter connected to the morphological
type (1)
96- 99 I4 --- Nmeas ? Number of measurements
101-102 I2 arcsec e_Pos Mean error on position
104-107 F4.2 mag e_Imag Mean error on Imag
109-113 F5.3 [0.1arcmin] e_logD Mean error on logD
115-119 F5.3 --- e_log(a/b) Mean error on log(a/b)
121-125 F5.1 deg e_PA Mean error on PA (2)
127-128 I2 --- e_MType Mean error on MType
--------------------------------------------------------------------------------
Note (1): Roughly: MType <0.1 for early (E), MType>0.1 for late (Sm)
Note (2): Note that the position angle is given even for nearly face-on
galaxies. It is thus important to consider the associated mean error
