Optical photometric, optical spectroscopic, and X-ray follow-up of extragalactic eROSITA sources showing X-ray changes

We followed up many eROSITA-selected X-ray sources which showed significant changes in their X-ray flux from one eRASS scan to another over the last years (still ongoing). The follow-up includes optical photometric and optical spectroscopic data from various telescopes, as well as X-ray follow-up data (mainly XMM-Newton and Swift). The database, hosted at the AIP, contains an overview of obtained data and additional information about the objects (X-ray and optical light curves, notes about the detection, etc.). Everyone in eROSITA_DE is welcome to access these data and use them. If you are interested, please send an email to dhoman@aip.de and mkrumpe@aip.de. We are of course also happy to provide you a short introduction about the usage of the data base.
