Cut-out of the 0.5−2.0 keV Chandra X-ray surface brightness map of the Bullet Cluster. The solid wedges represent the sectors employed to derive the hyperbolic shape best-matching the shock front geometry. The maximum-a-posteriori model is shown as a dashed line, while the dotted contours indicate the corresponding 95% credible interval. Further, the dashed and solid yellow circles denote respectively the ACA and ALMA full-width-at-half-maximum fields of view. For reference, the upstream and downstream gas lie respectively west (right) and east (left) of the shock front.
