Notes. The parameters of the models are the same as in Table 3, except Γ and kpl, index and normalisation of the power law component, the latter is in units of [ph keV-1 cm-2 s-1]. We show one row for each observation whenever no line was found at the 6 keV range, since in this case the two models 1c and 2c or 1d and 2d are the same model. For SAX J1808.4 − 3658 we show results for two spectra, which only differ in the pile-up treatment (see text).
