Notes. (1) PGMW # ID (Parker et al. 1992); (2) spectral-type classification (SpC); log of the number of ionizing photons per second for (3) H (QH); (4) He I (Q He I); and (5) He II models (Q He II) without considering X-rays; and QHe II considering X-rays (+XR).(a)Parker et al. (1992); (b)PAC priv. comm.;(c)Evans et al. (2006). (†)Stars analyzed in this work to quantify the total Q of the O-type stars in N11 B. For the remaining stars, the Q value from the object with the closest spectral type is assumed. The total ionizing photons by the 25 O-type stars in N11 B are estimated.
