CO(3–2) channel maps of the galaxy NGC 4826. The velocity relative to the systemic velocity of the galaxy (v_hel = 402 km s^-1) is given at the top left of each map. The phase center indicated by the large cross is at α_J2000 = 12^h56^m43.76^s, δ_J2000 = 21°40′51.9″. The galactic nucleus is marked by the small cross. The beam (represented at the bottom left of each map) is 2.6″ × 1.9″ and the rms is 75 mJy beam^-1. The only contour line overlaid corresponds to the 4σ level.
