Caption: Fig. 3.

Three spectra of the TOP star 507433 taken with UVES in slit mode (top), FLAMES‐UVES (middle), and GIRAFFE‐MEDUSA (bottom). All spectra are normalized using linear rectification curves. The UVES spectrum suffers from data reduction problems as discussed in § 2.3. Both the FLAMES‐UVES and the GIRAFFE‐MEDUSA spectra indicate an effective temperature of ﹩T_{\mathrm{eff}\,}=6260﹩ K.
