Mock NuSTAR spectrum of bright X-ray binary generated from our Kerr-like wormhole theoretical reflection spectrum with throat parameter λ = 0 (which corresponds to a rapidly rotating Kerr black hole with a_* = 0.998), folded through realistic NuSTAR RMF and ARF and background files, and fitted with our wormhole convolution model kwconv*xillverCp. Top: Folded spectrum with the best-fit kwconv*xillverCp (Kerr-like wormhole model) model overplotted. Bottom: Data-to-model residuals expressed in units of the data error, (data − model)/error.
