# SPARC raw source files

These files are preserved unchanged as the observational source layer.

- `SPARC_Lelli2016c.mrt` — 175-galaxy catalogue and quality metadata.
- `MassModels_Lelli2016c.mrt` — combined radial mass-model table.
- `Rotmod_LTG.zip` — 175 individual per-galaxy mass-model files.

The preparation code reads only these local files. It does not download, alter, or overwrite them.

## v0.3 project interpretation

This document belongs to the external transfer experiment. Numerical, technical, protocol, or provenance content above is preserved. The transfer result tests one static global architecture: it does not negate the galaxy-specific structural information carried by the curves. Complete curves retain identity, and ρ is the leading channel for local or regime-conditioned follow-up.
