How jordydavelaar/raptor works

RAPTOR computes relativistic images and spectra from GRMHD simulation data or analytic plasma models. The main workflow reads model parameters and a simulation snapshot, traces photon paths, transports radiation, then writes image and spectrum products for analysis. The README also documents polarized and unpolarized transport, adaptive or static camera grids, multiple model and metric options, and Python tools for plotting, FITS conversion, time series, and parameter inference. Core wiring is inferred only where the README or sampled entry point supports it; unsampled module internals are not mapped in detail.
