A sea-level base has been established for ING, in collaboration with the Galileo and Nordic telescopes. This is located in Edificio Mayantigo, close to the harbour in Santa Cruz de La Palma (picture, map).
In addition to offices for staff, the sea-level base provides accomodation, library and computing facilities for visiting observers. Visiting observers are encouraged to spend some time at sea-level, for pre-observation planning and/or post-observation data reduction. This should be particularly valuable as a way of improving contacts between the observatory and the user community.
