Broad-band spectrum of V404 Cyg of a simultaneous Swift/XRT (blue), INTEGRAL JEM-X (orange), and ISGRI (red) observation during an X-ray flare JF2d (see Fig. 3). The spectrum can be described by a partially covered Comptonized continuum or, as shown here, by the mytorus model (Yaqoob 2012), which describes a thick toroidal reprocessor that scatters the emission of a point-like X-ray source located at the geometrical centre of the torus. The spectral component dominating at high energies is produced by the emission transmitted through a column of N_H ≈ 1 × 10²⁴ cm⁻² (dashed line). The dot-dashed line marks the direct Comptonization emission from the source, while the dotted line represents the emission scattered within the toroidal reprocessor before reaching the observer.
