This work was supported in part by the National Science Foundation Grant DUE-0535839. We thank the students and staff of the participating schools and universities for their contributions in the acquisition of the data. We also thank Jason Soohoo and Richard Crowley for their help in setting up the automated retrieval of the data each day via internet connections. In addition, we also thank M. Lekberg, J. Cadigan, and M. Needles for their work in starting the MOSAIC project. We are deeply indebted to the reviewers of our paper who motivated us to obtain the large SABER and MLS datasets for comparison. We acknowledge and thank the SABER and EOS MLS teams for making their data available via the Internet.
