1990AJ....100..373R STAR FORMATION IN SPIRAL GALAXIES I. H{alpha} OBSERVATIONS W. ROMANISHIN Department of Physics and Astronomy, University of Oklahoma, Norman, Oklahoma 73019 Received 28 March 1990 ABSTRACT We present large aperture photometric measurements of H{alpha} + [N II] emission line strengths in 110 spiral galaxies. These galaxies represent three different samples of objects: (1) low surface brightness spiral galaxies, (2) galaxies of extreme arm classifications (flocculent versus grand design), and (3) galaxies with measured (B - H) colors which have been used to study the color-absolute magnitude relation for spiral galaxies. Details of the observations are given, and comparison made with previous work. Future papers will use this data to study the star-formation rates in the various samples.
