Table information for 'spec.data'

General

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

Resource Description: This collection is comprised of spectra from many different researchers, observatories and instrumental configurations. Most of them were used in publications (bibcode indicated at column "Ref.").
