The ESO Science Archive Facility contains the description of all observations performed with:

• The SOFI, SUSI2, EMMI instruments (on the NTT telescope at La Silla) since April 1, 1997
• The WFI, FEROS instruments (on the MPG-ESO 2.2m telescope at La Silla) since January 1999
• The EFOSC2, TIMMI2, CES, HARPS instruments (on the ESO 3.6m telescope at La Silla) since August 1999
• The instruments on the VLT/VLTI telescopes (at Paranal) since April 1, 1999
• The instruments on the APEX submm telescope (at Chajnantor) since July 11, 2005

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
• Observational domains (spectral and spatial resolution versus wavelength)
• Spectroscopic and imaging modes

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.
