¹²CO(1–0) velocity channel maps observed with the IRAM PdBI+30 m in the nucleus of NGC 3627, with a spatial resolution of 21  ×  13 (HPBW). The maps are centered on the phase tracking center of our observations (α_J2000 = 11^h20^m15.02^s, δ_J2000 = 12°59′2950) assumed to be coincident with the dynamical center of the galaxy. Velocity channels range from ΔV =  −200   km   s^-1 to  + 200   km   s^-1 in steps of 5   km   s^-1 relative to V_sys,hel = 744 km s^-1 (see Sect. 4.1). The contours run from  − 40   mJy   beam^-1 to 260   mJy   beam^-1 with spacings of 60   mJy   beam^-1.
