Ratio between the expansion speed v_exp and the translation speed v_trans of the CME, as a function of the heliocentric distances. The reconstructed value in the corona (at 14.9 solar radii, corresponding to 0.07 au) from Paper I is indicated as a magenta diamond. The observed value at Wind is indicated as a blue diamond. Reference values measured in the corona (< 0.1 au, from Gopalswamy et al. 2009a) and at 1 au (from Lugaz et al. 2020) are indicated as green and orange dashed lines, respectively. The location of the EUHFORIA heliospheric inner boundary is indicated by the dashed vertical grey line.
