ROSID - ROSAT SIMBAD Identifications

ROSID - ROSAT SIMBAD Identifications


Overview

The ROSID database is a byproduct of the ROSAT project. ROSID is a catalog of astronomical objects created from the SIMBAD database. It is used by the ROSAT project to generate the source lists which accompany processed ROSAT observations.

Each ROSID entry contains a source name and coordinates along with other information about the source. An earlier version of the ROSID database was restricted to a subset of the present database which coincided with a ROSAT pointing. The current version is the full database. Thus, although an object appears in the ROSID catalog, it does not imply that the object was either detected by or in the field of view of ROSAT.
