TAP (Table Access Protocol) service

WARNING: This tool is intended for advanced users. Basic knowledge of TAP and ADQL standards is required.
Remember that hardware resources are not unlimited, so please don't abuse of this service, otherwise we will have to block your IP address.
If you need to retrieve large result sets the asynchronous mode is preferred. For a better user experience we suggest to call this service using TOPCAT.
