Table Description:
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.
For ROSAT data products, see http://www.xray.mpe.mpg.de/cgi-bin/rosat/rosat-survey
For a list of all services and tables belonging to this table's resource, see Information on resource 'ROSAT results'
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:
