GRAMSCI: GRAph Made Statistics for Cosmological Information
Year: 2026
Type: article
Abstract: What's new in 2.5.0 Added Exact signed-volume parity (-exactparity): the odd-channel sign is computed from the exact galaxy positions rather than quantized spoke directions, eliminating direction-pixel attenuation entirely (recovered asymmetry consistent with unity for every tetrahedron family, including near-degenerate flattened and sheared shapes) at ~1.1–1.2× query cost. Runtime direction-pixel grid (-ntheta/-nphi) for the pixelized parity mode; pixel indices are now 16-bit (products up to 32767 pixels). Delete-one jackknife resampling for the 3PCF (CPU and GPU). GitHub Actions CI. Changed The default parity direction grid is now 8 × 32 (was 4 × 16), removing the recovered-asymmetry attenuation of near-degenerate configurations at <10% extra query cost. Full history in CHANGELOG.md.
