Notes

  • Use the global selector at the top to view all plots for a specific energy or compare two energies
  • Each plot also has an individual selector if you want to view different energies for different plots
  • The comparison modes show plots side by side for easy comparison
  • All plots are generated from Monte Carlo simulations of Lambda production and decay in the EIC detector
