资源简介：
This dataset contains processed outputs from SPARC galaxy rotation curve data (175 galaxies).
Each galaxy contains:- radius R (kpc)- observed velocity Vobs (km/s)- baryonic components (Vgas, Vdisk, Vbul)
Derived quantity:Vextra^2 = Vobs^2 - (Vgas^2 + Vdisk^2 + Vbul^2)
Processing steps:1. normalization of residual velocity field2. binning in radial coordinate3. stacking across galaxies4. null tests via shuffling
All results are reproducible using provided preprocessing code.
Reproduction requires:- Python 3.10+- numpy, pandas, matplotlib- SPARC dataset (Lelli et al.)
