Details on Acronym:   4XMM
   4XMM (4th catalogue of serendipitous X-ray sources found with XMM-Newton) Write:<<4XMM JHHMMSS.s+DDMMSS>> N: about 800000 Object:Any  (SIMBAD class: X = X-ray Source) Note:The XMM-Newton Survey Science Centre generates catalogs of serendipitous X-ray sources detected in archival X-ray observations of XMM-Newton. Re-processing of all observations will form the basis of 4XMM. It is a logical continuation of 1XMM, 2XMM, and 3XMM, all based on full reprocessing of all observations with most up-to-date software and calibration.

In the same spirit we would like to register 4XMMs for the stacked version of sources (similar to 3XMMs, that was registered 22 October 2018).
