Demonstrates new methods for reconstructing rotation curves in SPARC galaxies, indicating improved accuracy in measurements.
Deterministic reconstruction of SPARC galaxy rotation curves using a fixed operator framework. This release includes:- reconstruct_sparc.py (core reconstruction)- avity_plot_generator.py (plot generation) Reproduces Tier 1 galaxy fits with ~0.004 dex RMS residuals. To verify the reconstruction: Download the SPARC dataset Place galaxy files in a data/ directory Run: python reconstruct_sparc.py UGC06973 Expected result: RMS ≈ 0.004 dex Reconstructed rotation curve generated No parameter tuning required Data source:SPARC (Lelli et al. 2016)http://astroweb.cwru.edu/SPARC/ GitHub repository:https://github.com/kirbyproffitt-ux/SPARC-AVITY-Reconstruction
