Caption: Simulated Athena/X-IFU 25 ks spectrum for the archetypal ultra-luminous X-ray source NGC 1313 X-1. The spectral model is a power-law (Γ=1.9 and L_{[0.3:10 keV]} = 10⁴⁰ erg/s) absorbed by an ultra-fast outflowing gas in photoionization equilibrium with velocity 0.19c, N_H = 10²² cm^-2, log(xi)=2.34 and turbulent velocity of 500 km/s (FWHM). The emission lines are produced by a collisionally-ionized equilibrium plasma model with T=1.3 keV (the temperature of the collisionally-ionized gas) and L_{[0.3:10 keV]} = 10³⁹ erg/s (solar abundances are adopted for both the absorbing and emitting gas, see Pinto et al. 2016). Prominent blue shifted absorption and rest-frame emission lines are shown.

Additional comments: The response matrix and effective area file (XIFU_CC_BASELINECONF_2018_10_10.*) as well as background requirements (July 2018) are adopted.
