DRO classification performance for varying cylinder radii r and height z. For ‘background’ versus ‘hot center’ classification (a), performance saturation occurs at percentiles above the volume fraction of the ‘hot center’ cylinder, as defined by Z_sat,HC%. For ‘background’ versus ‘cold cylinder’ classification (b), performance saturation occurs at percentiles below the volume fraction of the ‘cold center’ cylinder, as defined by Z_sat,CC%. For ‘background versus ‘hot center’ with spoilers classification (c), performance is highest around Z_min,SP% and drops significantly above Z_max,SP%.
