Left panel: computed accretion luminosities (in units of 10³⁸ erg s⁻¹) for thefive spectral states of Cyg X-3 are shown for three clumping filling factors f = f_vol = 1.0 (dotted lines), = 0.3 (dashed lines), and = 0.1 (solid lines). The orbital angle Φ = 0 deg for the upper curves and Φ = 30 deg for the lower ones. The filled squares show the EQPAIR model luminosities (L_bol of Table A.1) The compact star mass is 2.4 M_⊙. In the abscissa 0 indicates NOX (no X-rays), 1 hard, 2 soft nonthermal, 3 intermediate, 4 ultrasoft, and 5 very high state. Right panel: same as in the left panel, but the compact star mass is 3.0 M_⊙.
