# RST Lensing Refraction — Results Output from **[[RST Lensing - Code]]** and **[[RST Refractive Lensing - Code]]**. --- ## What Is Shown - **Illustration:** Deflection vs impact parameter: GR scaling ($\propto 1/r$) vs RST disformal correction. The **derived** disformal term $(e^{2q}-e^{-2q})A_\mu A_\nu$ ([[RST Lensing (Disformal)]]) is the Refraction Identity; light is deflected by bandwidth congestion (workload $q$), not by a dark matter halo. - **Solver:** Galaxy-cluster lensing: RST deflection (with bending boost from workload $q$) vs Newtonian (baryons only). Proves the disformal refraction produces the extra bending required for clusters. --- ## Output | Output | Description | |:---|:---| | Refraction illustration | Deflection: GR vs RST (dimensionless) | | Refractive solver | Deflection vs impact parameter (kpc): RST vs baryons-only (Refraction Identity) | --- ## Status **Derived** (Baseline 1.7) per [[RST Baseline 1.0]], [[RST Charter (Scientific Status)]]. The disformal metric and bending boost follow from A1, A2, A4 and the Congestion Identity.
