Information on Service 'GAMA DR3 Datalink Service'

Spectra from the third data release (DR3) of GAMA.

Service Documentation

GAMA (Galaxy And Mass Assembly) is a joint European-Australasian project based on spectroscopic observations using the AAOmega multi-object spectrograph on the Anglo-Australian Telescope (AAT).

This resource contains the spectra from the third data release of GAMA, for more information, please visit the GAMA web site [1].

Notes

We ingested all the spectra from the SpecAll.fits table (i.e. not the rows with xxx as URL) except 7 files that did not contain actual spectra; these are the SDSS spectra with SPECID 318630249967413248, 318630524845320192, 318715736996472832, 318800674269718528, 340069354064340992, 369430722538137600, and 601252573990643712.

This leads to 214 341 available spectra.

We also added to the spectra the IS_BEST and IS_SBEST information from the SpecAll.fits table from the GAMA web site.

The SSAP response contains this columns: spectral, flux, error, flux_nocalib, error_nocalib, and sky. Nevertheless, not all spectra contain all the information, in particular the calibrated flux is not available everywhere.

ACKNOWLEDGEMENTS

GAMA is a joint European-Australasian project based around a spectroscopic campaign using the Anglo-Australian Telescope. The GAMA input catalogue is based on data taken from the Sloan Digital Sky Survey and the UKIRT Infrared Deep Sky Survey. Complementary imaging of the GAMA regions is being obtained by a number of independent survey programmes including GALEX MIS, VST KiDS, VISTA VIKING, WISE, Herschel-ATLAS, GMRT and ASKAP providing UV to radio coverage. GAMA is funded by the STFC (UK), the ARC (Australia), the AAO, and the participating institutions. The GAMA website is http://www.gama-survey.org/ .

Overview

You can access this service using:

dlget -- a datalink interface letting specialized clients retrieve parts of datasets or discover related data. You use this kind of service exclusively in combination with a pubdid, usually via a direct link.
dlmeta -- a datalink interface for discovering access options (processed data, related datasets...) for a dataset. You usually need a publisherDID to use this kind of service. For special applications, the base URL of this service might still come handy: https://vo.lam.fr/gama_dr3/q/sdl/dlmeta

This service is not published. This can mean that it was deemed too unimportant, for internal use only, or is just a helper for a published service. Equally likely, however, it is under development, abandoned in development or otherwise unfinished. Exercise caution.

Other services provided on the underlying data include:

Input Fields

The following fields are available to provide input to the service (with some renderers, some of these fields may be unavailable):

Name	Table Head	Description	Unit	UCD
ID	Id	The publisher DID of the dataset of interest	N/A	meta.id;meta.main
maxrec	Match limit	Maximum number of records returned. Pass 0 to retrieve service parameters.	N/A	N/A
responseformat	Output Format	File format requested for output.	N/A	meta.code.mime
verb	Verbosity	Exhaustiveness of column selection. VERB=1 only returns the most important columns, VERB=2 selects the columns deemed useful to the average user, VERB=3 returns a table with all available columns.	N/A	N/A
