In both cases, we resolve the component stars to be separated by a few milliarcseconds. The data were collected in the H-band, and provide a measure of the fractional flux for both stars in each system. We find that the WR star is the dominant H-band light source in both systems ($f_{\\rm WR, 137} = 0.59\\pm0.04$; $f_{\\rm WR, 138} = 0.67\\pm0.01$), which is confirmed through both comparisons with estimated fundamental parameters for WR stars and O","authors_text":"Anthony F.
