J/A+A/428/837       HII regions in minor mergers of galaxies   (Ferreiro+, 2004)

Sample of minor mergers of galaxies: Optical CCD surface photometry and HII region properties. Ferreiro D.L., Pastoriza M.G. <Astron. Astrophys. 428, 837 (2004)> =2004A&A...428..837F
ADC_Keywords: H II regions ; Galaxies, photometry ; Photometry, surface ; Morphology Keywords: galaxies: photometry - galaxies: interactions - galaxies: irregular Abstract: We present the results of the B, V and I photometry of eleven southern minor mergers. The total apparent B magnitude, integrated B-V and V-I colours were measured. We built B, V, and I equivalent profiles for each galaxy and decomposed them into bulge and disk components when possible. From Hα+N[II] images we have estimated the basic photometric parameters of the HII regions, such as position, size, B-V and V-I colours, Hα+[NII] luminosity and EW(Hα+[NII]) equivalent width. Description: The observations were taken in 1999 July using a Tektronix 2048x2048 CCD attached to the Cerro Tololo Inter-American Observatory 0.90m telescope. File Summary:
