Chandra Transmission Grating Catalog and Archive (TGCat) is back online

We are pleased to announce that the Chandra Transmission Grating Catalog and Archive (TGCat), which makes grating spectra easily viewable and accessible, is back online. The site went down for an extended period in order to implement major infrastructure upgrades. While there are no new features, users may encounter residual bugs.

If you have problems, suggestions, or encounter any bugs, please email us at tg...@space.mit.edu.

 

If you are unfamiliar with TGCat, you can learn more about it at: http://tgcat.mit.edu/about.php

The Chandra Transmission Grating Catalog and Archive (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.
