1. High Energy Stereoscopic System
ID:
ivo://vopdc.obspm/luth/hess
Title:
High Energy Stereoscopic System
Short Name:
H.E.S.S.
Date:
10 Jan 2017
Publisher:
Paris Astronomical Data Centre - LUTH
Description:
H.E.S.S. is a system of Imaging Atmospheric Cherenkov Telescopes that investigates cosmic gamma rays in the 100 GeV to 100 TeV energy range. The name H.E.S.S. stands for High Energy Stereoscopic System.
2. NED cross-IDs for object name
ID:
ivo://ned.ipac/NED_Names_for_Object
Title:
NED cross-IDs for object name
Short Name:
NED_names
Date:
07 Sep 2022 22:01:00
Publisher:
NASA/IPAC Extragalactic Database
Description:
NED service to retrieve Cross-IDs for a named object. It retrieves the names of sources which have been cross-identified with the named object. NED is built around a master list of extragalactic objects, for which multi-wavelength cross-identifications have been established. Cross-identifications are based on a statistical, rule-based cross-matching algorithm that matches names, positions, redshifts, and other relevant data to objects already in NED. These matches are also vetted by human experts on the NED staff.
3. NED diameters for object name
ID:
ivo://ned.ipac/Diameters_Data_by_Objects_Name
Title:
NED diameters for object name
Short Name:
NED_diameters
Date:
07 Sep 2022 22:01:00
Publisher:
NASA/IPAC Extragalactic Database
Description:
NED service to retrieve diameters, axis ratios, and position angles for a named object. Diameters and related data, measured across the electromagnetic spectrum, have been collected from large surveys, compilations and the literature. These include optical diameters from SDSS, GALEX, RC3, ESO-B, ESO-LV, UGC, MCG, and many others.
4. NED image data atlas
ID:
ivo://ned.ipac/SIA
Title:
NED image data atlas
Short Name:
NED_SIA
Date:
07 Sep 2022 22:01:00
Publisher:
NASA/IPAC Extragalactic Database
Description:
NED service to search for images in NED by Object Name or by position and radius, or refcode.
5. NED notes for object name
ID:
ivo://ned.ipac/Notes_By_Object_Name
Title:
NED notes for object name
Short Name:
NED_notes
Date:
07 Sep 2022 22:01:00
Publisher:
NASA/IPAC Extragalactic Database
Description:
NED service to retrieve notes, collected from various catalogs and journal articles, for a named object.
6. NED positions for object name
ID:
ivo://ned.ipac/Position_Data_By_Object_Name
Title:
NED positions for object name
Short Name:
NED_positions
Date:
07 Sep 2022 22:01:00
Publisher:
NASA/IPAC Extragalactic Database
Description:
NED service to retrieve Positions for a named object.
7. NED redshifts for object name
ID:
ivo://ned.ipac/Redshift_By_Object_Name
Title:
NED redshifts for object name
Short Name:
NED_redshift
Date:
07 Sep 2022 22:01:00
Publisher:
NASA/IPAC Extragalactic Database
Description:
NED service to retrieve redshift measurement for a named object in NED.
8. NED SED Data Discovery Service
ID:
ivo://ned.ipac/SED_Data_Near_Position
Title:
NED SED Data Discovery Service
Short Name:
NED_SED
Date:
07 Sep 2022 22:01:00
Publisher:
NASA/IPAC Extragalactic Database
Description:
NED SED Information Discovery Request service: This service retrieves photometry for objects within a specified radius of a given position. The search region is specified by two parameters: POS [RA and DEC in decimal degrees, ICRF/FK5J2000] and SIZE [degrees]. This service returns a list of NED Object Identifiers (Names), the count of photometric SED measurements for each object, and the URI (ACREF) for the SED Data Retrieval request (accessSED). This service is used by the VO SED analysis tool Iris.
9. NED SED Data for object name
ID:
ivo://ned.ipac/SED_Data_objname
Title:
NED SED Data for object name
Short Name:
NED_SED_data
Date:
07 Sep 2022 22:01:00
Publisher:
NASA/IPAC Extragalactic Database
Description:
NED service to retrieve Photometry for a named object. This service retrieves photometric data for a named object. The data include continuum measurements spanning the entire observed spectrum (radio through gamma rays). Measurements are provided in their published units, and they are also converted to common units to construct spectral energy distributions.
10. NED simple cone search
ID:
