The Peculiar Extragalactic System NGC 6438
Abstract
The peculiar interacting system NGC 6438 has been investigated at the Cerro Tololo Inter-American Observatory. It is shown that the irregular component and the SO component have about the same redshift velocity of +2400 km s- , so that the large velocity differences originally reported by Sersic are not confirmed.
