Figure 4:Example outputs from SoFiA for ESO 444-G047. Left: Extracted spectrum. Middle: Integrated HI column density map overlaid on to DECam (Müller, Jerjen & Binggeli 2015) image. The contour levels are 3, 5, 7, 9, 11, and 13 × NHI,sen in cm−2, which corresponds to colour scale of blue, orange, red, purple, pink, and olive green, respectively. Right: Velocity field, where only pixels above 3 × NHI,sen are plotted.
