Spectra from NuSTAR, XMM, and IXPE I, collected in May 2022, November 2022, and April 2025 for MCG-05-23-16, along with the best-fit model components for each instrument (shown only for the May 2022 campaign, when the source was observed simultaneous by all three instruments) and the residuals from the broadband (2–79 keV) spectral analysis in Sect. 3.2. Photon counting detector modules from NuSTAR (FPMA and FPMB) and IXPE DUs from the same campaign are grouped together for visual clarity.
