Subtracted spectra of the proposed tertiary for the HR02, HR04 and HR05 regions. We have not included HR03 due to its low signal-to-noise (discussed in the text), or HR06 as it is relatively featureless. Close examination of this spectrum may show reveal the presence of over-subtracted metal lines, but these are artifacts due to the use of a specific model spectrum from our grid with mean surface abundances a little different from the final abundance determination of the primary. Spectra were approximately normalized using a low order polynomial fitted to continuum regions.
