Resolve whether opacity or magnetic-field elevation causes the observed canopy displacement

Determine whether the apparent elevation of the magnetic canopy above solar striations is caused by an increased opacity gradient or represents a genuine geometrical elevation of the magnetic field.

Background

The reconstructed atmospheric cuts show that the canopy-like magnetic field is detected at different optical depths inside and outside dark striations. Outside the striations, the field appears from approximately $\log(\tau)=-0.8$ upward, whereas above a striation it appears closer to $\log(\tau)=-1.8$.

Because the inversion provides stratification in optical-depth coordinates rather than direct geometrical height, the observed displacement may arise either from changes in opacity or from a real elevation of the field structure. The available inversion results do not distinguish these explanations.
