The graph shows the number of papers that use data generated by other facilities (non-VLT/VLTI) of the La Silla Paranal (LSP) Observatory, including VISTA at Paranal as well as La Silla telescopes and instruments. Included are also visitor instruments for which observing time is recommended by the ESO OPO (Observing Programmes Office). Papers based on data from non-ESO telescopes or observations obtained during ‘private’ periods are not included.
Instrument-level information for La Silla facilities is available starting in publication year 2000.
