XMM-Newton spectral-fit database


This project provides a spectral-fit database (XMMFITCAT) for all the pipeline-extracted spectra within the XMM-Newton serendipitous source catalogue. The main goal is to provide the astronomical community with a tool to query the catalogue according to spectral properties and thus, to construct large and representative samples of X-ray sources fulfilling the spectral criteria.

This project is funded by the ESA-PRODEX program and consists of the collaboration between the X-ray Astronomy and Cosmology group group at the Istitute for Astronomy, Astrophysics, Space Applications, and Remote Sensing (IAASARS) at the National Observatory of Athens (NOA), the X-ray and Observational Astronomy Group (XROA) at the Department of Physics and Astronomy at the University of Leicester, the Galaxies and AGNs group at the Istituto de Física de Cantabria, and the XMM-Newton Science Survey Centre (SSC) .

April 2017 XMMFITCAT has been updated to 3XMM-DR6.

May 2016 XMMFITCAT has been updated to 3XMM-DR5, and a new project XMMFITCAT-Z has started.

June 2015 The XMMFITCAT FITS table has been modified, see Catalogue access for a description of the changes.

December 2014 New publication describing the construction of the database: XMMFITCAT: The XMM-Newton spectral-fit database.

November 2014 The list of spectra from the 3XMM-DR4 catalogue used in the spectral fits can be retrieved from here.

August 2014 XMMFITCAT can now be queried from LEDAS, see Catalogue access.

August 2014 XMM-SDSS tables updated.

August 2014 New publication, and talk added.

March 2014 The first full version of the XMM-Newton spectral-fit database can be retrieved from this page.

March 2014 The spectral-fitting results corresponding to a XMM/SDSS cross-correlation can be retrieved from this page.


Any publication based on data from the XMM-Newton spectral-fit database should have a reference to Corral et al. (2015), A&A, 576, 61, and also acknowledge the use of this database as well as the use of XMM-newton data in the acknowledgement section:

"Based on spectral-fitting results from the XMM-Newton spectral-fit database, an ESA PRODEX funded project, based in turn on observations obtained with XMM-Newton, an ESA science mission with instruments and contributions directly funded by ESA Member States and NASA".
