Combined spectrum of SS 433 accumulated over PV phase observations. Both blue-shifted and red-shifted lines of highly ionized (H-like and He-like) heavy elements (in particular, silicon, sulfur, iron, and nickel) are visible and come from the approaching and receding collimated baryonic jets. The model of multi-temperature cooling jets (Khabibullin et al. 2016) is able to the fit the data very well, although some excess emission is observed between 6 and 7 keV, probably coming from lower ionization species of iron existing in the accretion disk funnel or wind (e.g., Marshall et al. 2002; Brinkmann et al. 2005; Medvedev & Fabrika 2010; Medvedev et al. 2019).
