TAP_OBS is the ESO Science Archive TAP endpoint for observations (raw and reduced data) and ambient measurements (atmospheric seeing, turbulence, water vapour, relative humidity, air pressure, etc.) taken at the La Silla Paranal Observatory, including the Chajnantor (APEX) data. The Table Access Protocol (TAP) lets you execute queries against our database tables, and inspect various metadata. Table Upload is not currently supported, though it is foreseen for a next release. The IVOA ObsCore standard service is also provided (table name: ivoa.ObsCore), but currently only for reduced data. Other tables exposed are the dbo.raw describing all the LPO observations, the ambient tables (in the asm schema), plus the provenance table to close the loop between the raw and the reduced data, but also to describe the relationships between reduced data (e.g. a source table originating from a reduced image, etc.).

    A sibling service (TAP_CAT, endpoint: http://archive.eso.org/tap_cat) exists and can be used to query the astronomical catalogs produced by the principal investigators of ESO programmes (ESO public surveys included).
