top numbers in brackets = photon science related publication numbers as listed here 
bottom numbers in brackets include further FLASH machine related publications (statistics starting 2012), not listed here, but, e.g., in the DESY publication database.

Important for reporting: Publications marked with an asterisk are published in journals which are not included in the Thomson-Reuter (WOS) master journal list or Scopus journal list. Presently these are publications 181 & 201 (both 2013) and 435 & 436 (both 2023).
