Table information for 'rosat.photons'


Table Description: A table of x-ray photons detected by ROSAT

This table is available for ADQL queries and through the TAP endpoint.

Resource Description:

ROSAT was an orbiting x-ray observatory active in the 1990s. We provide a table of all photons observed during ROSAT's all-sky survey (RASS) as well as images of both survey and pointed observations.

Citing this table

This table has an associated publication. If you use data from it, it may be appropriate to reference 2000IAUC.7432R...1V (ADS BibTeX entry for the publication) either in addition to or instead of the service reference.

To cite the table as such, we suggest the following BibTeX entry:

  title={{ROSAT} results},
  author={Voges, W. and Aschenbach, B. and Boller, Th. and Brauninger, H. and Briel, U. and Burkert, W. and Dennerl, K. and Englhauser, J. and Gruber, R. and Haberl, F. and Hartner, G. and Hasinger, G. and Pfeffermann, E. and Pietsch, W. and Predehl, P. and Schmitt, J. and Trumper, J. and Zimmermann, U.},
