TGCat

The Chandra Grating-Data Archive and Catalog (TGCat) makes grating spectra easily viewable and accessible. The browse-able 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.
