资源简介:

This dataset contains rotation curve measurements and derived lens-mass scaling analyses for three galaxies: NGC 6503, UGC 2885, and NGC 801. These data were used to examine the radial dependence of mass scaling factors when matching rotation-curve–based enclosed mass to the effective lensing mass corresponding to an Einstein radius of θ_E = 1.47 arcsec (based on SDSS J0037–0942 lens geometry: Dl=669 Mpc, Ds=1412 Mpc, Dls=922 Mpc). The key result is that all three galaxies show a similar monotonic decrease in the scale_mass_to_match factor as radius increases, without requiring galaxy-specific tuning of dark matter halo profiles. This suggests that an additional term contributing to gravitational curvature—interpretable as an information density component—may vary systematically with radius. Included in this release:- Observational rotation curve data (CSV)- Processed and radius-swept scale-vs-radius results (CSV)- Reproduction scripts (Python)- Figures (scale-vs-radius and rotation curve overlays)- Short technical note summarizing the procedure and findings (PDF) This dataset is provided to support reproducibility, reanalysis, and further theoretical or observational study.
