EFEDSMAIN - eROSITA Final Equatorial Depth Survey (eFEDS) Main X-Ray (0.2-2.3 keV) Source Catalog |
HEASARC Archive |
Overview
The eROSITA X-ray telescope on board the Spectrum-Roentgen-Gamma (SRG) observatory combines a large field of view and collecting area in the energy range ~0.2 to ~8.0 keV with the capability to perform uniform scanning observations of large sky areas. SRG/eROSITA performed scanning observations of the ~140 square degrees eROSITA Final Equatorial Depth Survey (eFEDS) field as part of its performance verification phase. The observing time was chosen to slightly exceed the depth of equatorial fields after the completion of the eROSITA all-sky survey. The authors present a catalog of detected X-ray sources in the eFEDS field providing source positions and extent information, as well as fluxes in multiple energy bands and document a suite of tools and procedures developed for eROSITA data processing and analysis, validated and optimized by the eFEDS work.A multi-stage source detection procedure was optimized and calibrated by performing realistic simulations of the eROSITA eFEDS observations. The authors cross-matched the eROSITA eFEDS source catalog with previous XMM-ATLAS observations, confirming excellent agreement of the eROSITA and XMM-ATLAS source fluxes.
This table presents the primary catalog of 27910 X-ray sources, including 542 with significant spatial extent, detected in the 0.2-2.3 keV energy range with detection likelihoods >=6 , corresponding to a (point source) flux limit of ~6.5 x 10-15 erg/cm2/s in the 0.5-2.0 keV energy band (80% completeness). The linked EFEDSHARD table presents the hard band sample of 246 sources detected in the energy range 2.3-5.0 keV above a detection likelihood of 10. A supplementary catalog contains 4774 low-significance source candidates with detection likelihoods between 5 and 6. The dedicated data analysis software package, calibration database, and calibrated data products are described in an appendix.
Additional information for the eROSITA early data release observations is available at the eROSITA-DE EDR website.

Provenance
This database table was originally ingested by the HEASARC in August 2022 and is based upon the "eROSITA/eFEDS main catalogue" file downloaded from the eROSITA-DE Early Data Release catalogs web page. It was revised in June 2024 in order to rename the right ascension, declination, and their related positional uncertainty parameters to match the parameter naming convention used in other eROSITA catalogs. In some cases, the HEASARC has altered the original field names, as per HEASARC conventions, and provides the original field names in square brackets.Parameters
