Synthetic optical (top) and UV (bottom) spectra of the 200 M_⊙ models at Z = 0.1 Z_⊙. The left (right) panels correspond to models without (with) metallicity scaling of the mass-loss rates. In all panels, the spectra from top to bottom correspond to models with 0.01, 0.5, 1, 1.5, 2, and 2.5(2.2) Myr as marked by squares on the evolutionary track in Fig. 1 and with parameters given in Tables A.3 and A.4. Spectra are shifted vertically for clarity.
