- Description:
- The eROSITA-DE DR1 comprises data from the first six months of the SRG/eROSITA all-sky survey (eRASS1) whose proprietary rights lie with the German eROSITA consortium. Data rights are split by Galactic longitude (l) and latitude (b), with a division marked by the great circle passing through the Galactic poles (l,b)=(0,+90);(0,-90) and the Galactic Center Sgr A* (l,b)=(359.94423568,-0.04616002): data with -0.05576432< l <179.94423568 degrees (Eastern Galactic hemisphere) belong to the Russian consortium, while data with 359.94423568 > l >179.94423568 degrees (Western Galactic hemisphere) belong to eROSITA-DE. The Western Galactic hemisphere observations were released to the public through the <a href="https://erosita.mpe.mpg.de/dr1/">eROSITA-DE site</a> on 31 January 2024. In the Early Data Release (EDR), the data taken during the Calibration and Performance Verification (Cal-PV) phase were released and are available in <a href="/W3Browse/erosita/erosmaster.html">EROSMASTER</a>. The reprocessed EDR observations are not part of DR1. The primary data products of the eROSITA-DE DR1 consist of calibrated event files, which contain the information generated by the cameras used during the eRASS1 observations. The eSASS4DR1 pipeline creates these event files after the received telemetry data from eROSITA of each observation has been reformatted, packaged, and archived by a pre-processor. Note that the coverage of the sky is not uniform, i.e., not all observations have been performed with all seven eROSITA telescope modules (TMs). The eROSITA-DE team has divided the eRASS1 observations into 4700 sky tiles for practical purposes. Each sky tile has a size of 3.6x3.6 square degrees, overlapping by approximately 20 arcmin. Of the 4700 sky tiles, eROSITA-DE have proprietary rights on 2248 of them, and 199 sky tiles have shared rights between the German and Russian consortiums. eROSITA-DE DR1 comprises 2447 sky tiles in total, of which 199 have partial eROSITA-DE data. The FITS table here, provides the mapping between sky-tile identification and sky coordinates for the 2447 sky tiles. In addition, the 0.2-2.3 (<a href="/W3Browse/erosita/erass1main.html">ERASS1MAIN</a>) and 2.3-5 keV (3-band; <a href="/W3Browse/erosita/erass1hard.html">ERASS1HARD</a>) source catalogs are also available. This database table was created by the HEASARC in August 2024 based on the FITS file of the survey field boundaries available from the eROSITA-DE <a href="https://erosita.mpe.mpg.de/dr1/AllSkySurveyData_dr1/">DR1 site</a>.

- Description:
- This is the eROSITA Master Catalog which has been created from information supplied to the HEASARC by the <a href="https://erosita.mpe.mpg.de/edr/eROSITAObservations/">eROSITA-DE</a> team. This database table contains the list of observations made by the SRG eROSITA mission. Currently, the German eROSITA Consortium (eROSITA-DE) has made public the observations obtained during the Calibration and Performance Verification (Cal-PV) program for which it holds data exploitation rights. Over one hundred individual pointing and field scans were performed with eROSITA as a prime instrument between mid-September and mid-December 2019 form part of the Cal-PV program. For practical purposes, the eROSITA-DE team has divided the Cal-PV observations into four categories: <pre> Survey fields: These are scan observations of large, contiguous areas of the sky. Magellanic Clouds: These are observations around the Small and Large Magellanic Clouds. Galactic fields: These include observations with |Galactic latitude| < 17 deg. Extragalactic fields: These include observations with |Galactic latitude| > 17 deg. </pre> The HEASARC has created this database table, based on the observations from the shared public data, and added links to associated <a href="https://heasarc.gsfc.nasa.gov/db-perl/W3Browse/w3table.pl?MissionHelp=srg-erosita">eROSITA</a> catalogs and data products, where available. The HEASARC produced this database table based on information obtained from the eROSITA-DE website in July 2023. This is a service provided by NASA HEASARC .
