When should I use the ESO Archive interface or the VLT general query form and when the instrument specific ones?
The ESO Archive interface is intended to aid general queries, especially to astronomers with no previous experience with ESO telescopes and instruments. The general form is advisable for searches by object and to browse the archive contents for all the observations independent of wavelength range and observing mode (e.g. imaging, spectrum). The instrument specific pages will help in finding observations which are either specific to the observing strategy, like stacks in the infrared, or to the detector or instrument setups. These pages should be used when you are searching for specific data (e.g. infrared spectra) for a given object or when you are searching individual observation programs. • Hints on how to improve your search strategy • Do a general search first, look at the result and use values from the result table to refine your query; gradually narrow down your search. • On the query forms one can select the columns that appear in the tabular output. So, mark all fields which ar
