Notes. Column 1: Observation time. Column 2: The heliocentric distance of the CME nose. Columns 3–5: Rmin, R̄c, and Rmax are the minimal, mean, and maximal ROCs of the CME nose, respectively. Uncertainties of ROCs are computed with 100 Monte Carlo simulations. Column 6: The heliocentric distance of the shock apex. Column 7: The standoff distance (Δ) between the CME nose and the shock apex from the bow-shock fitting. Column 8: The SDR, δ, normalized by R̄c. Columns 9–11: The Alfvén Mach number, Alfvén speed, and magnetic field strength of the ambient corona calculated with R̄c.
