Hα profile morphology in the VLT-FLAMES data (top two profiles) and SALT-HRS data (four lower profiles). Spectra have been off-set by 0.5 normalized flux units for clarity. Sharp emission features in the SALT-HRS data are night sky lines (⊗). Hα and the sky line just long-ward of 6590 Å are likely blended with weak nebular H I and [N II] respectively, as discussed in the text. The position of the central dip of the Hα Doppler core of the narrow-lined B-type star is indicated, as are the positions of its two C II lines (↑).
