Left: 3D rendering of Hyperion, as defined by the VMC technique. Right: 2D projections of Hyperion in the (top) R.A.-Dec., (middle) R.A.-z, and (bottom) Dec.-z planes. In all panels, the contours delineate regions of differing overdensity within the VMC map. The purple and green shaded regions correspond to Hyperion’s outskirts (2.5 ≤ n_σ ≤ 4.0) and peaks (n_σ ≥ 4.0), respectively, where n_σ is defined in Equation (2). Also shown in red are regions with n_σ ≥ 5.0, which generally trace the most massive peaks of Hyperion (detailed in Table A.1).
