Spectra of three observed contaminants to our sample. Top: Spectrum of SMC4, a carbon star. The spectrum is characterised by two molecular carbon bands and several strong, deep P Cygni profiles. Middle: Spectrum of SMC5, a late M giant star. Strong TiO bands are revealed in the red part of the spectrum, indicating a low effective temperature. From the Ca II triplet, only λ8662 is present, albeit almost completely blended in with the overarching TiO band. Bottom: Spectrum of LMC9, an ionised nebula. The overall spectrum is dominated by strong emission lines coming from a nebula. Strong [O III] was detected, and the Hα emission was saturated. The emission line profile of Hα shows significant broadening, and other circumstellar lines (Fe II) were detected in the left wing of Hα, revealing an LBVc.
