More information on instrumentation is available from the following online resources:

• Instrumentation at the Paranal observatory site
• Instrumentation at the La Silla observatory site
• Instrumentation at the Chajnantor observatory site
• Overview of global observing capabilities

You may also query the database of ESO filters, or the database of ESO & HST Science Instrumental Characteristics to find out, for example, which ESO filters fall within a standard bandpass.

Characteristic curves may also be accessed through the ESO Instrument Exposure Time Calculators.

Quality checks of data and instrument trendings are available from the ESO Quality Control pages.
