Sensitivity of the glitch parameters in the damped oscillator model (Eq. 10) to the input physics of MESA models. The labelling follows that in Fig. B.1, except that the modulation phase differences ΔΦ_gl between the reference and modified models are given by ΔΦ_gl = Φ_gl, mod − Φ_gl, ref, where Φ_gl, ref and Φ_gl, mod are the modulation phases found in the reference and modified models, respectively.
