Surface photometry and spectral analysis of Mk50 - A Seyfert 1 nucleus in an early type galaxy
Markarian 50 is analyzed using V and I CCD frames and IPCS and CCD spectra, obtained in June 1985, covering the range 3200-10,000 A. It is inferred from the surface brightness profiles derived from the images that this is an early-type, elliptical, or S0 galaxy, which is supported by the spectral analysis of the stellar population.
