Arcsecond Positions of UGC Galaxies
We present accurate B1950 and J2000 positions for all confirmed galaxiesin the Uppsala General Catalog (UGC). The positions were measuredvisually from Digitized Sky Survey images with rms uncertaintiesσ<=[(1.2")2+(θ/100)2]1/2,where θ is the major-axis diameter. We compared each galaxymeasured with the original UGC description to ensure high reliability.The full position list is available in the electronic version only.

Galaxy coordinates. II. Accurate equatorial coordinates for 17298 galaxies
Using images of the Digitized Sky Survey we measured coodinates for17298 galaxies having poorly defined coordinates. As a control, wemeasured with the same method 1522 galaxies having accurate coordinates.The comparison with our own measurements shows that the accuracy of themethod is about 6 arcsec on each axis (RA and DEC).

Isophotal twisting in isolated elliptical galaxies
Luminosity, ellipticity, and position angle profiles of 43 ellipticalgalaxies selected from the UGC catalog are used to study isophotaltwisting not arising from the intrinsic structure of the object.Isolated galaxies have been chosen to avoid distortions of the isophotesdue to the occurrence of tidal effects of photometric overlapping withclose companions. It is demonstrated that isophotal twisting occurs inisolated galaxies with about the same frequency as for objects inrandomly selected samples. Objects having luminosity profiles close tothe exp 1/4 law show no twist of the isophotes within the errors,whereas any degree of twist is allowed when more complex luminosityprofiles are observed.
