Abstract

The Submillimeter Array (SMA) is an 8-element interferometer which operates in the 180-700 GHz range located atop Mauna Kea in Hawaii. It is a collaborative project between the Smithsonian Astrophysical Observatory (SAO) and the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA) and is funded by the Smithsonian Institution and the Academia Sinica. The University of Hawaii (UH) receives a fixed percentage of all time on the telescopes of Mauna Kea. As such, the observing time at the SMA is shared among these partners at the SAO:ASIAA:UH levels of 72:15:13. The nature of interferometric observing makes keeping track of these partner shares challenging. Since a typical successful interferometric observation could last anywhere from 3-10 hours for it to have sufficient uv-coverage, it does not necessarily make sense to divide the observing time up simply by counting hours. In this talk I will summarize the strategy devised at the SMA for keeping track of partner time shares as well as the tools used to make these numbers transparent to all affiliations.
