Notes. gau1/edge1 models the emission feature at  ~ 1 keV with a Gaussian component or an edge, respectively. kTbb and kTdbb are the temperatures of the blackbody and disc blackbody components respectively. kbb, kdbb, and kgau are the normalisations of the blackbody, disc blackbody, and gau1 components in units of (Rin/D10)2, (Rin/D10)2 cosθ and 10-4 ph cm-2 s-1 respectively. Egau and σ represent the energy and width of the Gaussian feature. Eedge is the edge energy and τ its optical depth. F9 is the unabsorbed 2 − 10 keV total flux in units of 10-9 erg cm-2 s-1. We show two rows per observation corresponding to fits with Models 1a and 2a, except for observations for which no significant emission was found at the 6 keV range, since in this case Models 1a and 2a are the same model, namely tbabs*(bbrad+dbb+gau1/edge1)+gau3+gau4. We do not show the values of gau3 and gau4, since they are fixed calibration features. The parametres of gau2 and laor components are shown in Table 5. The spectrum energy range is 1.5–10, 1.8 − 10 and 2.2 − 10 keV for 4U 1705 − 44, 4U 1728 − 34 and GX 340 + 0, respectively, and 0.7 − 10 keV otherwise (see text).
