Excerpts of BOSS spectral fits of He-poor hot subdwarfs. From top to bottom: SDSSJ124248.89+133632.6 (sdB), SDSSJ124310.58+343358.4 (sdOB), SDSSJ124819.08+035003.2 (sdO). In the upper panels the best-fit synthetic spectrum (red) is shown along with the observed one. The lower panels give residual χ, whereby the long-dashed horizontal lines mark the zero values and the short-dashed horizontal lines mark the deviations in terms of 1σ. Parts of the spectra, which have been excluded from the fits, are marked in grey.
