Caption: Figure 3.
Comparison of temporal and spectral features. Top row (light curves): arms show noise-like variability, cosmic-ray events show sharp temporal impulses, and true sources show astrophysical variability. Bottom row (spectra): arms show background spectra, cosmic-ray events show hard spectra (>2 keV), and true sources typically show softer spectra.
