Based on observations collected at the German-Spanish Atronomical Center, Calar Alto, Spain, operated by the Max­Planck-lnstitut für Astronomie (MPIA), Heidelberg, jointly with the Spanish National Commision for Astronomy. The authors are indebted to J. Gorgas for his continuous cooperation, valuable ideas and careful read­ing of the manuscript. This work was supported in part by the Spanish Programa Sectorial de Promoción General del Conocimiento under grant PB93-456.We present the results of Thuan & Gunn r CCD imaging observations of the Universidad Complutense de Madrid (UCM) sample of emission-line galaxies (ELGs), selected by the presence of H_α emission in low-resolution objective prism spectra. In this work we characterize photometrically and morphologically a total of 212 objects from the UCM survey. This Paper presents the observations and basic reductions, and lists a set of photometric parameters calculated for each UCM object. In addition, for the first time in a ELGs sample, we have determined the morphological classification of the objects using simultaneously five different criteria.engjournal articlehttp://dx.doi.org/10.1051/aas:1996178http://aas.aanda.org/open access52Emission-line galaxiesCCD surface photometryNorth galactic poleTo-disk ratiosComa superclusterSpiral galaxiesSky surveyCatalogObjectsClusterAstrofísicaAstronomía (Física)
