2003ApJS..147...29G Palomar/Las Campanas Imaging Atlas of Blue Compact Dwarf Galaxies. I. Images and Integrated Photometry Gil de Paz, A. ; Madore, B. F.; Pevunova, O. Abstract. We present B, R, and H{alpha} images for a total of 114 nearby galaxies (V_helio_<4000 km s^-1^) that, with exception of nine objects, are classified as blue compact dwarfs (BCDs). BR integrated magnitudes, H{alpha} fluxes and H{alpha} 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 criteria include a limit on the K-band luminosity (I.e., stellar mass; M_K_>-21 mag), peak surface brightness ({mu}_B,peak_<22 mag arcsec^-2^), and color at the peak surface brightness ({mu}_B,peak_-{mu}_R,peak_<~1). H{alpha} emission is detected in all but three sample galaxies. Typical color, absolute magnitude, and H{alpha} luminosity are (B-R)=0.7+/-0.3 mag, M_B_=-16.1+/-1.4 mag, and log (L_H{alpha}_)=40.0+/-0.6 (ergs s^-1^). Galaxies morphologically classified as nE and iE BCDs within our sample show lower H{alpha} equivalent widths and redder colors, on average, than the iI- and i0-type BCDs. For most of the galaxies the presence of an evolved stellar population is required to explain their observed properties; only the most metal-poor BCDs (e.g., I Zw 18, Tol 65) are still compatible with a pure, young burst. The flux-calibrated and WCS-compliant images in this Atlas are individually available through the NASA/IPAC Extragalactic Database (NED) image server and collectively through a dedicated Web page.
