Dipole mode visibility of the central pressure radial order (i.e., 192 to 208 μHz) calculated using the normalized power spectrum p for the set of stellar parameters A. The modulus of the reflection coefficients of the outer boundaries are set to |R_p| = 0.95 and |R_g| = 1. Colors indicate the period spacing. The values on the horizontal axis correspond to deviations from assumption made by Mosser et al. (2017) measured by v (Eq. (D.3)).
