DO ELLIPTIC GALAXIES SUFFER FROM WARP

The present work includes the performance of detailed surface isophotometry of NGC 1700. Luminosity profiles, ellipticity curve, reduced luminosity profiles and the galaxy parameters are illustrated; the study includes the variation of position angle with the distance from the centre of the galaxy as well. An interesting feature of this object is the twisted shape of the outer isophote which does not appear as an ellipse but as an integral-sign shape which attributed to some kind of warp in the galaxy under investigation. © 1990 Kluwer Academic Publishers.
