Plain black line: fitting of the RV map obtained from the observations done on September 14, 2009 without taking account of the atmospheric seeing on RV profiles. Gray lines: mean zonal wind on the visible part of the dayside of Venus as computed from model 7 based on the observations done on September 14, 2009. In other words, it is the mean of the map shown in Fig 18, bottom panel, with 100 executions to take into account the errors on the parameters of the model. The black dashed line indicates the average mean profile of model 7.
