SPARC–4DEU Galaxy Rotation-Curve Fits: Supplementary Data for 0.05 and 0.707 Thresholds

These Excel files correspond to supplementary analyses related to the publication: Maglione, D. (2026). Galactic Rotation Curves Explained in the 4DEU Framework by 3D Spatial Curvature from Local Gravitational Blocking of Cosmic Expansion: No Need for Dark Matter. Journal of High Energy Physics, Gravitation and Cosmology, 12, 431-470. https://www.scirp.org/pdf/jhepgc_2181492.pdf Each Excel file contains the complete fitting results obtained by repeating the full 4DEU fitting procedure using alternative dominance criteria (0.05 and 0.707).These datasets were used solely to compare the stability of the fitted parameters, their statistical correlations, and the goodness-of-fit properties across different thresholds, in order to justify the adoption of the intermediate operational value 0.5 used in the main analysis.
