The upper two rows show projected handedness H_proj and sign asymmetry (left), and the extrinsic handedness dipole A_dip and axial sign asymmetry (right). The lower row shows spirality for all accepted FANS and the two- and three-arm subsamples, separately for the Carrón sample (left) and the Chen sample (right). Blue dashed and red dotted curves denote the Carrón and Chen samples, respectively. Markers are centered at the mean redshift of each bin, horizontal bars span the bin boundaries, and vertical bars show the 1σ uncertainties obtained from a spatial block bootstrap with N_side = 16. Triangles at the left margin show the measurements over the full unbinned range 0.1 < z < 0.6. In the parity-sensitive panels, gray envelopes indicate the 1σ and 2σ equivalent ranges of the block sign-flip null ensembles, with dashed boundaries for the Carrón sample and dotted boundaries for the Chen sample. The quoted significances refer to the full-range unbinned measurements. The continuous observables are expressed in degrees by applying ﹩\arcsin (x)﹩. The final Chen three-arm point is omitted because too few objects are available for a reliable estimate. The fitted axes are (α, δ) = (329^∘, 62^∘) for the Carrón sample and (198^∘, 50^∘) for the Chen sample; neither dipole is statistically significant, with global significances of <0.1σ and 0.4σ for the full-range handedness dipole amplitude ∣A_dip∣ in the Carrón and Chen samples, respectively.
