H i spatial and kinematic information for AGC198606. Upper row: WSRT data at 210′′ resolution. Lower row: WSRT data at 105′′ resolution. Left column: velocity field from Gaussian fitting to 4.2 km s^-1 spectral data cubes with H i column density contours overlaid. The contours are [0.5, 0.75, 1.5, 2.5, 4] and [1.25, 1.75, 2.5, 3.5, 5] × 10¹⁹ atoms cm^-2 for the 210′′ (upper) and 105′′ (lower) data. Middle column: velocity dispersion map of AGC198606 from the Gaussian fitting. Contours show lines of constant velocity from the velocity fields (left) and are at values of [41, 43.5, 46, 48.5, 51, 53.5, 56] km s^-1. Right column: position-velocity slice along the major axis (shown in left panels). Contours are spaced at 3σ; for the 210′′ and 105′′ data σ is 2.11 and 1.07 mJy beam^-1. The dashed line is the recessional velocity cz = 50.9 km s^-1; the solid lines are offset by ± 12.5 km s^-1.
