Luminosities in the 20 cm and 5 cm bands from our per spectral window data (red points). The solid green curve is the simulated emission considering acceleration by MR, and synchrotron emission suffering free-free absorption in the stellar wind. We also include data points from Taylor et al. (1996) (grey triangle) and Benaglia & Ishwara-Chandra (priv. comm., observed in Oct. 2014, yellow circle), and from O’Connor et al. (2005) for the total flux density (dark grey squares) and the WR emission (orange squares). The straight lines represent the separated (dashed) and summed (solid) free-free emission from the winds using Eq. (8) from Wright & Barlow (1975).
