Apep NuSTAR spectra in the 3–35 keV energy range. The spectra were further rebinned in XSPEC for clarity. The source spectrum is shown with crosses and the background spectrum with open circles. Top panel: Spectra for the 2022a and 2022b observations showing each camera separately. Middle panel: Spectrum from the co-added observations from both epochs (for each camera separately). Bottom panel: Spectrum from the co-added observations (both epochs, both cameras).
