 Usually, you don't have to worry about the details. But be aware, that data retrieval is a two-step procedure: 1) preparation for download ('​staging'​) and 2) the download itself. Also, take care not to request [[lta_faq#​what_is_an_appropriate_amount_of_data_to_retrieve?​| too much data at the same time.]] Usually, you don't have to worry about the details.

 In principle, yes, this is the only supported procedure, at the moment. There are development versions of programming interfaces, with which it is possible to query the catalog and talk to the staging service, e.g. from scripts. But these are not generally made available, unsupported and still in development. If you are an '​expert user', are self-dependent enough to figure out how to work with this, and have a good reason, please contact the [[https://​support.astron.nl/​rohelpdesk|Radio Observatory helpdesk]] for some instructions and an emphatic admonition to take extra care.  In principle, yes, this is the only supported procedure, at the moment.
