| Abstract | We present B, R, and Hα images for a total of 114 nearby galaxies (vhelio<4000 km s-1) that, with exception of nine objects, are classified as blue compact dwarfs (BCDs). BR integrated magnitudes, Hα fluxes and Hα equivalent widths for all the objects in the sample are presented. A new set of quantitative, observational criteria for a galaxy to be classified as a BCD is proposed. These criter ... |
