This resource describes the Simple Cone Search interface provided by TGCat. The Chandra Grating-Data Archive and Catalog (TGCat) makes grating spectra easily viewable and accessible. The browsable interface to analysis-quality spectral products (binned spectra and corresponding response files), with the addition of summary graphical products and model-independent flux properties tables make it easy to find observations of a particular object, type of object, or type of observation, to quickly assess the quality and potential usefulness of the spectra, and to download the data and responses as a package.

Available Service Interfaces

Simple Cone SearchXXSearch Me

This is a standard IVOA service that takes as input a position in the sky and a radius and returns catalog records with positions within that radius.

Available endpoints for the standard interface:
  • http://tgcat.mit.edu/tgCli.php?
Maximum search radius accepted: 180 degrees
Maximum number of matching records returned: 10000
This service supports the VERB input parameter:
Use VERB=1 to minimize the returned columns or VERB=3 to maximize.
