Example of simulated bulk+thermal Comptonization spectrum (red histogram) and the XSPEC model bmc1 * highcut1 + bmc2 * highcut2. The spectrum is shown in units of keV (keV cm ⁻²s ⁻¹keV ⁻¹) with absolute values that are multiplied by an arbitrary constant. The hard and soft components are shown by dash green and dash red curves, respectively. The resulting spectrum is shown by a solid green curve. In the simulations, the mass accretion rate in Eddington units is , C ₁/ C ₀ = 5, q = 0.01, and the flow electron temperature is kT _e = 2.4 keV.
