Hamburg/ESO service SSAP

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. The magnitude range covered is roughly between 18.5 and 11 mag in B_J.

This is a collection of uniformly reduced spectra prepared by Norbert Christlieb. It is also intended as a sort-of resolver for HES names (“identifiers“) like ”HE 2301-7732”; unfortunately, these identifiers are not unique. You will need to apply domain knowledge in order to find the object actually being referred to when resolving an identifier of this sort.

This is queryData for the default operation; some services support getData as well
Only return the TOP "best" records (on this service, this usually is equivalent to MAXREC, so no ranking is implied).
