Table 1
Minimum and maximum values of time-integrated energy (E) in erg, time-integrated number (Q) of the ionising photons and the time average value of the photon numbers per seconds for hydrogen (H), neutral helium (He) and singly ionised helium (He+) emitted during the main-sequence phase by our stellar evolutionary models (cf. Table B.1).

Notes. Black body radiation is assumed. For comparison, the ionising energy and photon numbers of the Pop III models of Yoon et al. (2012) are shown: these values are systematically higher than those of our corresponding models due to the higher effective temperatures of the metal-free models (see also Fig. 17).
