Table information for 'obscore_demo.datasets'

General

Table Description: Datasets (i.e. event lists, IRFs, and the like) produced by KM3NeT and ANTARES.

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: The provided demo dataset serves as an example use case of the keys provided in ObsCore and the high energy extension (HEA) of ObsCore for neutrino telescope data. The contained dataproducts cover the ANTARES legacy dataset and KM3NeT data and simulations.

For a list of all services and tables belonging to this table's resource, see Information on resource 'Test data set for ObsCore'
