1993ApJS...85...27M OPTICAL IMAGING AND LONG-SLIT SPECTROSCOPY OF MARKARIAN GALAXIES WITH MULTIPLE NUCLEI. I. BASIC DATA JOSEPH M. MAZZARELLA Infrared Processing and Analysis Center, 100-22, California Institute of Technology Jet Propulsion Laboratory, Pasadena CA 91125; Division of Physics, Mathemathics & Astronomy, California Institute of Technology and Department of Astronomy, University of Michigan, Ann Arbor AND TODD A. BOROSON Kitt Peak National Observatory National Optical Astronomy Observatories, P.O. Box 26732, Tucson, AZ 85726-6732 Received 1992 March 16; accepted 1992 July 15 ABSTRACT Optical CCD images and long-slit spectroscopic data are presented for over 100 Markarian (UV-excess) galaxies reported in early studies to possess multiple optical nuclei or extreme morphological peculiarities suggestive of galaxy collisions and mergers. Stacked broad-band (BVR) images are presented with histogram equalization in order to show simultaneously the nuclei and features at very low surface-brightness levels. Morphological properties, luminosities and colors of the integral systems are given. Photometric and image properties of over 200 individual nuclei and giant H II regions have been measured with respect to the local backgrounds in the galaxies using an objective image finding algorithm. Labeled contour plots identify the measured subcomponents. Two-dimensional spectral data are presented, in addition to intensity profiles along the slit in the light of H{alpha} + [N II] emission lines and adjacent continuum. Nuclear emission-line measurements (4500-7500 A, ~10 A FWHM resolution), reddening estimates, monochromatic continuum magnitudes, and colors are given. Interpretation of these data with emphasis on the confirmed interacting and merging galaxies is presented in a subsequent paper. Subject headings: galaxies: interactions - galaxies: nuclei - galaxies: photometry - galaxies: starburst
