  1. Δν is the large frequency separation, ΔΠ1 the gravity-mode period spacing, q the coupling parameter. The relative buoyancy radius \({x}^{*}={\widetilde{\omega }}_{g}^{*}/{\omega }_{g}\), amplitude A, and phase ε are the dimensionless parameters inferred from the fitting of the glitch-induced modulation, and τsig = ΔΠ1/x* is the period of the glitch signature. The glitch parameters x* and A are directly related to the position and amplitude of the discontinuity, respectively17, 30.
