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.
