English: 20 Stolz sectors for M = 1.01 to 10.
Python codeimport numpy as np
import matplotlib.pyplot as plt
M_values = np.linspace(1.01, 10, 20)
fig, ax = plt.subplots(1, 1, figsize=(10, 10))
for M in M_values:
x = np.linspace((1-M)/(1+M)+1e-6, 1-1e-6, 1000)
y = -(M**4 * (x**2 - 1) - 2 * M**2 * ((x - 1) * x + 1) + 2 * np.sqrt(M**4 * (-2 * M**2 * (x - 1) + 2 * x - 1)) + (x - 1)**2)/(M**2 - 1)**2
y = np.sqrt(y)
ax.plot(x, y, color='blue', alpha=0.5)
