Table information for 'hamburg_eso.data'

General

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

Resource Description: The Hamburg/ESO survey (HES) is a digital objective prism survey covering the total southern extragalactic sky. It is based on Kodak IIIa-J plates which have been taken with the 1m ESO Schmidt telescope and its 4° prism. The spectral coverage is 3200-5300 Å, at an resolution of 15 Å at H gamma. This is a collection of uniformly reduced spectra prepared by Norbert Christlieb.
