摘要：

We present large aperture photometric measurements of Hα + [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.
