Channel maps taken from the r10_t0 cube that has been smoothed with a 5 channel Hanning window and regridded to 3 km s⁻¹ channels. Every third 3 km s⁻¹ channel for a 170 km s⁻¹ range centred on the systemic velocity is shown. The blue contour indicates 3σ_rms, the greyscale contours are 3σ_rms × 2ⁿ, n = 2, 4, 6, ⋯. The magenta cross indicates the optical centre of the galaxy, and dotted magenta ellipse indicates the extent of the optical disk (D₂₅) of the galaxy. The green arrows point to “fingers” in the H I. The orange ellipse in the lower left corner of each panel represents the 21.6″ beam.
