IRSA Astronomy Archive: Cone Search a Catalogue

irsatap/cone-search

Finds sources within a radius of a sky position (right ascension and declination in decimal degrees, ICRS) in the 2MASS point source, 2MASS extended source or AllWISE source catalogue at the NASA/IPAC Infrared Science Archive. Returns up to 25 rows with every catalogue column. Data from IRSA, served by Eden Engine; not an official IRSA, NASA or Caltech product.

You pay the price shown. If a call turns out to cost more than its quote, you pay the actual price, capped at twice the quote. No monthly minimum. Top-ups start at $0.50.

Data source

NASA/IPAC Infrared Science Archive

Data from the NASA/IPAC Infrared Science Archive (IRSA), operated by IPAC at Caltech (irsa.ipac.caltech.edu). IRSA asks users to acknowledge the archive and the missions whose catalogues they use (for example 2MASS and WISE); suggested credit: "This research has made use of the NASA/IPAC Infrared Science Archive, which is funded by the National Aeronautics and Space Administration and operated by the California Institute of Technology." Served by Eden Engine; not an official IRSA, NASA or Caltech product.

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "irsatap/cone-search" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "irsatap/cone-search" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "irsatap/cone-search", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "irsatap/cone-search", input: { /* ... */ } })

// 5. settle: the call is charged when it finishes, nothing to do
