Two observed composite HERMES spectra taken at quadrature in the region of the Mg II 4481 Å spectral line. A broad and shallow spectral feature of the secondary component is clearly seen at about 1% of the continuum. A fiducial pseudo-continuum is indicated with the dashed line for reference. The spectra were obtained on BJD 2 459 286.64516 (red line) and BJD 2 459 305.62250 (blue line), and correspond to the phases of the orbital cycle 0.486 and 0.856, respectively.
