Comparison between our model and the flux densities at 5, 8.4, 23 GHz (“+” sign; uncertainty in the flux measurements are given by the length of the bars) of the binary system WR 113 obtained by Montes et al. (2009). We have assumed the stellar wind parameters Ṁ_WR = 2.0    × 10^-5   M_⊙   yr^-1, v_WR = 1700   km   s^-1, Ṁ_O = 0.4 × 10^-5   M_⊙   yr^-1, and v_O = 1800   km   s^-1. The stars are separated by a distance D ~ 0.6 AU. The dotted and dashed lines represent the fluxes (∝ ν^0.6) from the winds of the WR and O type stars, respectively. The radiation from the WCR (dot-dashed line) and the total flux density (solid line) from the binary source are also shown. The physical description of the plot is given in the text.
