HIPASS Hi column density contours are overlaid on the DSS2 (Digital Sky Survey 2) red optical image. Two small colored ellipses represent the optical size, position angle (PA), and the inclination of our targets, taken from de Vaucouleurs et al. (1991, RC3). ESO catalog names of our BCDs are presented in white with their systemic velocity. Two other optically identified galaxies in this field, which are background systems, are also annotated in black. The HIPASS Hi contour levels are (3, 6, 12, 24, 30) × 1018 cm-2. The primary beam of the Parkes telescope (14) is shown at the lower left corner. Three ATCA pointings, each of which corresponds to the size of the ATCA primary beam (33.1 arcmin in diameter) are indicated by the orange line. On the top right corner, the zoom-in DSS2 blue images of individual galaxies are presented. Each panel is the size of 2 × 2 arcmin2. Again, the colored ellipse represents the optical size and PA of each galaxy (de Vaucouleurs et al. 1991).
