Comparison of the high-energy detections of Tycho, with the Fermi 95% confidence error circle denoted in red (for photons of energy E > 1 GeV; from Giordano et al. 2012), the VERITAS error circle in green (for energies E > 1 TeV; from Acciari et al. 2011), and the NuSTAR 20–40 keV band contours in blue. The image is the background-subtracted NuSTAR 20–40 keV image smoothed with a Gaussian function of width σ = 5 pixels.
