Notes. All spectra normalised to I(Hα) = 100.0. The extinction value applied (from Hα/Hβ, assuming Te of 11 000 K, Ne of 1500 cm−3) for the 12 A quality spectra summed is c = 0.394, for the 42 A+B quality spectra summed c = 0.382 and for all 100 spectra summed c = 0.164. See Table 7 for the quality assignment of the freckle spectra.
