Morphological parameters against redshift. The parameters are plotted for the bright cluster subset (≥300 counts) with larger markers. The small markers show clusters with at least 25 counts, without plotting uncertainties. The colour scale shows the X-ray luminosity (log erg s⁻¹ in the 0.2–2.3 keV band) inside an aperture of radius 800 kpc. The parameters are the central scaled gas density (n_s, 0), central electron density (n₅₀), concentration from 80–800 kpc (c_{80 − 800}), concentration from 0.1R₅₀₀ to R₅₀₀ (c₅₀₀), central density slope (α), slope at fixed radius (α₅₀), ellipticity (ϵ), slosh (H), multiple magnitudes (M₁ to M₄), power ratios (P₁₀ to P₄₀), photon asymmetry (A_phot), centroid shift (w), Gini coefficient (G), and fit-peak offset (F).
