Spectral index maps at low- and high-frequency for NGC 2276 and its stripped tail. Both maps are Voronoi binned (Cappellari & Copin 2003) to a target of S/N = 15. In the upper left of each panel we list the uncertainty on the spectral index derived from the individual flux-calibration uncertainties (which is the dominant source of uncertainty given the high S/N from the Voronoi binning).
