Resonance conditions. Distribution of resonance points with \(R<10\) over time (a) and dependencies of \(R_{\text {min}} \le 5\) on time (b, c) for the whole packet. Dependencies \(R_{\text {min}}(\Theta _{L0},W_0)\) for the chosen time intervals: element 14, 10–25 s (case I, d), element 14, 45–60 s (case II, e), element 22, 25–40 s (case III, f). On the bottom panels the \(R_{\text {min}}\) scale is limited by \(R=10\)
