Left panel: montage of spectra of early-B hypergiants within the Quintuplet. The spectrum of the B1 Ia+ hypergiant BP Cru is provided for comparison (red; spectrum from Waisberg et al. 2017). Right panel: comparison of the B0–1 Ia+ star qF381 to the cluster WN10h star LHO67 and the WN11h star LHO71. Given the scale only prominent emission lines are shown; weaker transitions are indicated in Fig. 1. Where available HST/NICMOS F205W magnitudes are given in parentheses (Table A.1).
