Location of the selected horizontal planes for the statistical analysis.

Plane ln(p0/p) zK8V (km) zK2V (km) zG2V (km) zF5V (km)
Convection zone −0.5 −31 −57 −110 −206
Surface 0.0 0 −1 −2 −6
Middle photosphere 2.0 101 153 270 475
High photosphere 4.0 183 284 486 835

Notes. The values of z for each model correspond to the plane that best approximates the mean value of ln(p0/p) relative to the mean τR = 1 surface.
