MUSE maps: Hα flux, equivalent width, SFR density from H flux, stellar mass density from H-band, specific SFR, and velocity field. The position of SN 2009bb is indicated by the blue or red circle. The images are 50″ × 50″ (not the entire MUSE coverage). North is up and east is left. White indicates values above the maximum value in the colour bars. The velocities are relative to the systemic velocity of 2961 km s⁻¹.
