Approach for handling both filament and prominence boundary conditions within Lightweaver. Top panel; the cone-averaging approach employed to ensure proper sampling of the limb-darkening function with height. Bottom panels; the tracing of the base quadrature across the solar surface for both the filament (left) and prominence (right) cases. These panels consider a view top-down onto the solar surface from, for example, Solar Z = 1.3 R_⊙. This base quadrature sampling is augmented with the additional cones as shown in the top panel.
