Keck Observatory & Subaru Users Meeting Highlights 2014
The Keck Observatory and Subaru Users Meeting in 2014 showcased the benefits of their exchange program, enhancing scientific productivity. The event highlighted the unique wide-field and spectroscopic capabilities offered by both observatories, bringing their communities closer together and contributing to the Mauna Kea Observing System. The exchange program expanded observing capabilities and included advanced instruments like Suprime-Cam, MOIRCS, FOCAS, HDS, IRCS, FMOS, and more. This exchange program has been ongoing since 2007, fostering collaboration between Keck and Subaru communities.
