eROSITA Archive

eROSITA Archive Access

The Cal-PV program of the SRG mission took place between mid-September and mid-December 2019. During this Cal-PV phase, over one hundred individual pointings and field scans were performed with eROSITA as prime instrument. The CAL-PV observations that were proposed by eROSITA-DE are released to the public through the eROSITA-DE Early Data Release (EDR) as of June 28 2021.

The eROSITA catalogs can be accessed through the following HEASARC multi-mission interfaces:

HEASARC Browse interface	The classic multi-mission interface
HEASARC Xamin interface (including a command-line batch interface)	HEASARC next-generation multi-mission data portal
Astronomy data access through Python	Using Python and generic VO interfaces.

Around thirty different fields have been observed. There is a variety of covered areas and exposures. eROSITA-DE is releasing calibrated event lists for each observation so scientists around the world can use the data for their research. These data are provided here and additional information can be found from the eROSITA-DE EDR Observations page.

Moreover, the eROSITA-DE team has obtained source catalogs for some of these observations. Further details can be found at the eROSITA-DE EDR Catalogues page. The HEASARC has also ingested a number of these, see column with "Available Catalogs at HEASARC".

An important piece in X-ray analysis is the Filter Wheel Closed (FWC) data, which helps to assess the level of instrumental background. eROSITA-DE is also releasing FWC data and models here .

[1] On September 2021 it was discovered a calibration error in the photon arrival time correction (of 1 second) on approximately half of the TM6 data of eFEDS sub-field I before a malfunction. The error causes the photons to be projected onto the sky with an offset of ~13 arcsec on either side of the true source position, resulting in an elongation of the merged all camera PSF in the scanning direction in the affected area. The affected period spans from: UTC=2019-11-03 13:03:12.25 until UTC=2019-11-03 21:04:53.03. Users are advised to take this error into account. For more details check Brunner et al. 2021.
