COSMO #

COSMO is a tool for exploring astronomical data from the Gaia catalog.

You can try COSMO live at https://tedius.tngl.sh/cosmo/

Features #

  • Local/VizieR data: load your own local CSV file, or a TSV file exported from VizieR.
  • Table view: browse the raw data in a table format.
  • 2D plot: plot any two columns against each other with fully free axis selection.
  • 3D scatter plot: plot any three columns against each other with free axis selection.
  • 3D slice tool: move and resize a slice through the 3D scatter to inspect a specific slab of the data.

if you're using nix we have a flake.nix with a devShell with bun

bun install # install dev packages
bun run dev # dev server for instant changes preview
bun run build # compile the project to dist/

  • Some local files generate empty tables
  • Zoom in the 2D plot sometimes goes to infinite zoom on a star
  • Hover and clicked star colors in the table are applied to the star with index +1
