Comparison of Muon Spectra Using the CIC Method on Vertical Showers

The study applies the CIC method to KASCADE-Grande muon data, analyzing muon densities, spectra, and attenuation curves. Findings show good agreement in vertical showers. The CIC method is used to correct systematic uncertainties and determine muon numbers. Insights are gained by comparing simulated and CIC-obtained muon spectra.
