The Chandra X-ray Observatory Data Archive provides a reference survey
via the HiPS protocol.
For detailed information on the Chandra Observatory and datasets see:

The Chandra X-ray Observatory is the U.S. follow-on to the Einstein
Observatory. Chandra was formerly known as AXAF, the Advanced X-ray
Astrophysics Facility, but renamed by NASA in December, 1998.
Originally three instruments and a high-resolution mirror carried in
one spacecraft, the project was reworked in 1992 and 1993. The Chandra
spacecraft carries a high resolution mirror, two imaging detectors,
and two sets of transmission gratings. Important Chandra features are:
an order of magnitude improvement in spatial resolution, good
sensitivity from 0.1 to 10 keV, and the capability for high spectral
resolution observations over most of this range.

The SimDAL repository hosts numerical projects descriptions as standard XML documents following the Simulation Data Model serialization xsd. It allows clients to search (fulltext) for simulation projects or associated protocols of interest and get URIs towards other SimDAL components: SimDAL Search and SimDAL Data Access.
