Effect of microturbulence on the derived ΘRT when microturbulent broadening is not taken into account in the FT+GOF analysis. Black and gray curves indicate the derived ΘRT resulting from the FT+GOF analysis of a Si iii line synthesized assuming two different values of microturbulence (5 and 20 km s-1, respectively) and convolved to a fixed v sin i = 50 km s-1, and the ΘRT values indicated in abscissa.
