The goal is to provide a resource for the astronomical community that will be usable for observations with the largest ground-based and space-based optical detectors, both those that are currently in existence, and those under construction and in the planning stage. The specific goal is to extend faint calibration sequences by 5 magnitudes so that the limits of interpretation in data will be scientific, and not those of calibration.
