This directory contains the committed source payload for the gravity module.
-
```bash
sha256sum archive/src/gravity/raw/egm2008_n2_4.csv
wc -c archive/src/gravity/raw/egm2008_n2_4.csv
```
Compare those values with `../manifest.toml`.
Replace the CSV only together with an update to `../manifest.toml`, then run:
```bash
cd archive
cargo run -p archive-validate -- MANIFEST.toml
cargo check --features gravity
```
