Reduced samples of simulated glitches from an assumed parent distribution dN/dΔν ∝ Δν^−α with a perfect correlation Δτ_k + 1 = CΔν_k, with C = 0.21 yr μHz⁻¹. Top: resulting correlation between Δν_k and Δτ_k + 1. Bottom: corresponding distributions of logΔν for the reduced samples of glitches. For both panels, each colour (and point marker) represents a typical realization in the simulations, for different power-law exponents as shown in the legends.
