IRSA Astronomy Archive: Run an ADQL Query

irsatap/adql-query

Runs an ADQL (astronomical SQL) query against the NASA/IPAC Infrared Science Archive and returns the rows as objects keyed by column name, with the column list and units. Covers the 2MASS and WISE source catalogues and many other survey tables; add `TOP n` to the query and keep selections to the columns you need. Capped at 100 rows. Data from IRSA, served by Eden Engine; not an official IRSA, NASA or Caltech product.
