Table information for 'rosat.images'

General

Table Description: Metadata for ROSAT pointed observations and the ROSAT All Sky Survey (RASS) images

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
