^A Calculated in the spacecraft reference frame. Note that in a case of an FR shock, the spacecraft enters first to the downstream region.
^B We estimate T_e as a constant value, which depends only on the radial distance from the Sun. This may introduce errors (see documentation).
^C The shock normal determination is subject to several caveats (see documentation). The shock normal and the related parameters (M_A, M_ms, V_sh, θ_Bn) should be dealt with care.
^D Cluster 4 spacecraft was used only as a backup when both Cluster 1 and Cluster 3 had a data gap. The plasma measurements of Cluster 4 have lower quality and therefore the results based on them should be considered only as crude approximates (see documentation).
^E Error estimates of the parameters are based on the amount of fluctuations of the data over the analysis intervals (see documentation). In case of particularly large fluctuations error propagation may result in unrealistically large error estimates for some parameters. Such parameter values should be interpreted particularly carefully.
