A comparison of the 3pcf estimated using ConKer compared to existing methods. Top: edge-corrected 3pcf, , computed using ConKer (left column) and nbodykit (right column) up to l = 3. The color scale is applicable to all panels. Bottom: residual between the two methods, shown as a distribution over all (s₁, s₂) pairs for l = 0 (blue), l = 1 (yellow), l = 2 (green), and l = 3 (red).
