Channel maps binned 80 km s⁻¹ determined relative to the redshifted CO(1-0) transition assuming a redshift of z = 0.1555, consistent with that determined for the BCG in Donahue et al. (2010). The red contours correspond to the ≥2σ contours in the CO(1-0) moment = 0 map shown in the upper panel of Figure 4. The solid black contours correspond to the signal in each maps and start at 2σ significance. The channel maps were used to inform the region choices in Fig. 14.
