Overview of the HALOGAS observations of NGC 925. The panels are as in Fig. 3. The contours in the left panel begin at N_HI = 2.0 × 10¹⁹ cm^-2 and increase by powers of two. The grayscale in the right panel ranges from 440 km s^-1 (black) to 675 km s^-1 (white). Contours are white on the approaching side and black on the receding side, and run from 450 km s^-1 to 660 km s^-1 in steps of 15 km s^-1. The white contour closest to the center of the galaxy, corresponding to 555 km s^-1, represents the systemic velocity of NGC 925.
