Table 2.

Fit of the seismic parameters ε and d_0ℓ, and the dimensionless glitch parameters.

ℓ		A_ℓ	B_ℓ
0	ε	0.614 ± 0.002	0.578 ± 0.003
1	d₀₁	−0.081 ± 0.002	0.083 ± 0.005
2	d₀₂	0.156 ± 0.001	−0.031 ± 0.003
3	d₀₃	0.374 ± 0.002	−0.059 ± 0.005

Notes. The fits were performed for RGB stars alone. The acoustic offset and the reduced small separations were fitted by a linear fit A_ℓ + B_ℓ log(Δν), while the glitch parameters were fitted by a power law CΔν^D.
