As in Fig. 14, but now for a lower velocity channel (δv = +1.12 km s⁻¹), thus emphasizing the outer disk regions. Compared are the standard model without the outer disk cut-off (η = 1) in the top row, and the model with a steeper disk cut-off (η = 2) and resulting strong subKepler rotation in the bottom row. We note that this is the same velocity channel as used in Fig. 13, and the leftmost and rightmost panels of that figure are the same as the top-left and bottom-left panels here, respectively.
