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 visitor instruments for which observing time is recommended by the ESO OPC (Observing Programmes Committee). 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.
