Upper panels: comparison of the predicted RL profiles (H26α and H27α) by modelling the ionized disk and wind of MWC 349A with and without the ejected clumps (red and black lines) with a velocity of 35 km s^-1 in clumps located at a radius of r_l = 30.7 AU. Lower panel: predicted H27α profiles assuming that the region from which the wind is launched is located at r_l = 30.7 and 43 AU.
