There are currently no charges for use of the Keck equipment. However, the creation and future development of the Keck center relies on the generous support of the W. M. Keck Foundation. As such, for any papers that may arise from work performed in the Keck facility, please acknowledge the W. M. Keck Foundation and pass a copy of these papers along to Prof. McCammon so he can document the role of the facility in users' research.
Thank you for your help.
