astrostash

🔭 An astronomy and astrophysics database building/syncing tool

Astrostash lets you "stash" query results from astronomy data sources into a local SQLite3 database by caching individual queries, or mirroring entire catalog tables for offline access.

Features

• Local data storage — Retain copies of query results in a SQLite3 database.
• Offline querying — Mirror stable catalog tables and query them with spatial filters without network access.
• Automatic caching — Results from repeated queries are served from your local database.
• Refresh scheduling — Set a refresh interval to keep cached data up to date.
