Query Observation

The Advanced Search modules allow you to specify coordinates and further parameters of the Observation or Pipeline products that you are looking for.
A search on Observations will return the setup of the telescope at the time of observing, but is unlikely to return any downloadable data. Typically, only pipeline products are archived and these can be directly searched for by selecting the Pipeline modules. If you choose Observations, you will anyhow have the chance to jump to the relative pipelines.
