In 2018, for the second time in a row, the total number of data papers published by the ESO users community exceeded the 1000 mark, almost exactly matching the record high of the previous year (2017: 1090; 2018: 1093). In total, over 15 000 data papers have been published since 1996 (the year the ESO Telescope Bibliography started). In 2018, the number of papers using data from the VLT/VLTI, the ESO survey telescopes VISTA and VST, as well well as APEX were slightly below those of 2017, while data from the La Silla observing site led to even more data papers than in recent years*. The largest increase occurred for ALMA (taking into consideration only data obtained during European observing time), which generated 24% more papers than in 2017.
ESO Publication Statistics 2018
Statistics on refereed publications that make use of data from ESO telescopes have been published by the ESO library. The statistics are calculated using the ESO Telescope Bibliography (telbib), a database of refereed publications resulting from ESO data. The annual summary of publication statistics, with breakdown by telescopes and instruments and a comparison with other observatories, is available as Basic ESO Publication Statistics (DOI 10.18727/docs/1).
* La Silla statistics only include facilities for which observing time is recommended by the ESO Observing Programmes Committee; data papers from hosted telescopes are not included.
