The rms spectrum of the SALT campaign corrected for Galactic foreground extinction (red). Two power-law models are fitted to the continuum slope. The first considers only the continua at 5100 Å and bluewards giving a spectral index β = 2.61 ± 0.06 (black); the second considers all measured continua giving a spectral index β = 1.82 ± 0.03 (grey).
