Galaxy coordinates. III. Accurate positions for 17124 galaxies including 3301 new companions of UGC galaxies Paturel G., Petit C., Garnier R., Prugniel P. <Astron. Astrophys. Suppl. Ser. 144, 475 (2000)> =2000A&AS..144..475P 2000A&AS..144..475P
ADC_Keywords: Galaxy catalogs ; Positional data Keywords: galaxies - catalog Abstract: This paper gives accurate coordinates and diameters for 3301 galaxies, companions of UGC galaxies. (about 2764 companions were not yet available in electronic form). In addition previously poor equatorial coordinates are re-measured for 13823 galaxies. These coordinates which have an accuracy of 5'' or better will be used for facilitating the cross-identification with forthcoming catalogues of millions of galaxies.
