ROSAT query services

GAVO has implemented IVOA standard query services on various ROSAT archives. In particular, we have implemented simple cone searches (follow this link for the specification) on catalogues derived from the ROSAT All Sky Survey (RASS). The Bright and Faint Source Catalogues were loaded into a relational database and a simple query interface provides access to this database for performing a cone search. These catalogues are relatively small and could also be downloaded directly from the ROSAT archive at the Max-Planck-Institut für extraterrestrische Physik (MPE).

A new product GAVO offers is a cone-search on the photon event file, containing all the photons observed in the RASS. The same user interface offers query capabilities. The size of this catalogue, which contains about 100 million photons, put more requirements on the tuning and indexing of this database. For a description of the methodology we have used there can be found here.

We have also implemented the Simple Image Access Protocol (follow this this link for the specification) on all the ROSAT images, both the fields derived form the all sky survey and all the pointed opbservations.
