AB: The blind test exercise for the kinematic source inversion has been launched within the European project SPICE to investigate the robustness of the inversion procedures. Although the test was performed with noise free data and exactly known propagation models the quasi-linear inversion performed by several research groups led to significantly different slip maps. Here we systematically investigate the influence of the different components of the inversion procedure onto the final slip maps. We specifically analyze how the selection of a specific parametrization and a misfit function, the approximations in the forward modelling and the station distribution weigh on the non linearity and uniqueness of the solution. The assessment of the uncertainties is also discussed.
