Comparison of our FOCES spectrum (full line) with a longslit spectrum from the NStars project (Gray et al. 2003, dots) in the region of the Balmer lines Hγ to H8 for Deneb (A2 Ia) to assess the quality of the normalisation of our echelle spectra. Note that the FOCES spectrum was was artificially degraded in resolution to match the 1.8 Å resolution of the longslit data.
