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.
