X-ray scaling relations recovered from the halo population in the lightcone, with L₅₀₀ − M₅₀₀ in the left panel and kT₅₀₀ − M₅₀₀ in the right panel. The luminosity L₅₀₀ is intended as the IGrM-only emission including Galactic absorption in the 0.1 − 2.4 keV band within R₅₀₀. For reference, literature values are also reported. The masses and mass-weighted temperature were calculated in the same radius R₅₀₀. Considering the small redshift range, we neglected any evolutionary changes in the scaling.
