Technical Requirements for VLTI Visitor Instruments
The option to bring Visitor Instrument into the VLTI facility has been offered to permit innovative observations by teams using stand-alone instruments. The Visitor Instrument (VI) teams should in particular be able to react quickly to new scientific and/or technical opportunities. VIs are therefore free from a substantial fraction of the requirements imposed on VLTI facility instruments.
These documents are advanced draft versions. They are being updated and should serve as a basis for discussion until final versions are released. It is strongly recommended that a VI team double-check with ESO (through the contact person assigned to the instrument in question) all necessary details before designing critical items.
