Mock NuSTAR spectrum for a bright AGN or compact source generated from our Kerr-like wormhole reflection template with throat parameter λ = 0.9 and spin a_* = 0.998, folded through realistic NuSTAR RMF and ARF and background files, and fitted with the convolution model kwconv*xillverCp (Kerr-like wormhole model). Top: Folded spectrum with the best-fit kwconv*xillverCp model overplotted. Bottom: Data-to-model residuals in units of the data error, (data − model)/error.
