Figure 3: Spectroscopically confirmed N(WC)/N(WN) ratio for NGC 300, together with other nearby spiral (filled squares) and irregular (filled circles) galaxies from Crowther (2007) and references therein, plus Hadfield & Crowther (2007) for NGC 1313. Open symbols for NGC 300 and NGC 1313 are corrected for candidate WR sources, as outlined in the text. Predictions from Meynet & Maeder (2005, solid) and Eldridge & Vink (2006, dotted) are also shown. |
