Fig. 4.
ATCA+GMRT H I moment maps of the Fourcade-Figueroa galaxy. Top left panel: H I distribution overlaid on the DSS2 I-band image. The H I contour levels are 0.24, 0.9, 1.7, and 2.1 Jy beam−1 km s−1. Top right panel: H I distribution (same contours). Bottom left panel: velocity field, the contour levels are 768, 788, 808, 828, 848, 868, and 888 km s−1. Bottom right panel: velocity dispersion; the contour levels are 3, 8, 10, 12, and 15 km s−1. The H I distribution maps were made using the low-resolution cube with a synthesised beam of 20″ × 20″.
