+- Chiron requires Swiss Ephemeris asteroid ephemeris files in `./data/`.
+- The time-segmented files `seas_00.se1` through `seas_168.se1` cover Chiron from ~675 CE to ~4650 CE.
+- The files `sepl_*.se1` and `semo_*.se1` are needed for far-future dates (beyond 3000 CE).
+- If any of these files are missing, `get_planetary_positions` will still return the other bodies, but Chiron will error until the files are present.
+- All files are from the Swiss Ephemeris distribution (based on JPL DE441), available at https://github.com/aloistr/swisseph/tree/master/ephe
