Diagram showing the plane of progenitor star initial mass and metallicity. Shaded areas are stellar evolution predictions from rotating single-star models of Georgy et al. (2009), for SN II (pink), Ib (light green), and Ic (blue-green). Data points from this work are colour-coded: blue for SN Ic, bright green for Ib, red for II, purple for IIn, orange for IIb, and cyan forIcBL. Uncertainties in metallicity reflect the 0.16 dex error in the 12 + log(O/H) N2 calibration of Marino et al. (2013).
