ESO publication statistics are derived from the Telescope Bibliography (telbib), a database of refereed papers that directly use ESO data. For further information, see also the document on Basic ESO Publication Statistics which is available from the ESO Libraries homepage.

Publication statistics given in the table below are linked to the corresponding papers in telbib.

Notes:

VLT/VLTI: papers using data generated by VLT and VLTI instruments, including visitor instruments for which observing time has been evaluated by the ESO OPO (Observing Proposals Office).

LSP others: papers using data generated by other facilities of the La Silla Paranal Observatory, including visitor instruments for which observing time has been evaluated by the ESO OPO. Papers based on data from non-ESO telescopes or observations obtained during 'private' periods are not included.

Survey telescopes: papers using data generated by ESO's survey telescopes (VISTA and, in future, VST).

APEX: papers using data generated by APEX, including visitor instruments for which observing time has been evaluated by the ESO OPO. Other visitor instruments are exluded. Only papers based (entirely or partly) on ESO APEX are included.

ALMA: papers using data generated by ALMA. Only papers based (entirely or partly) on ESO ALMA time are included.

Total: the total number of papers per year from all observing sites, following the restrictions mentioned above. Papers can use data from more than one facility, therefore the total number cannot be calculated by adding all publications of the individual sites.
