baryon acoustic feature

Today was an all-day meeting regarding this new project (as yet un-named) to measure the baryon acoustic feature at multiple redshifts to determine the expansion history of the Universe and the physical properties of the dark energy, using the SDSS Telescope after SDSS-II operations complete. A large group from Princeton, LBNL, MIT, Harvard, CITA, CWRU, and NYU (plus Arizona, FNAL, and Portsmouth by phone) converged here at NYU to discuss the science, the technical requirements, funding (of course), and data reduction and management. It was wonderfully productive, but I was talked into shepherding the requirements document.
