Fed Bianco (NYU) gave a great astro seminar today at NYU about the LSST project. She focused on time-domain and transient aspects, but did a good job of discussing the methods for making objective trade-offs in the cadence and survey-strategy space. Arguments broke out about filters and about data access. That was interesting and valuable. The project is amazingly ambitious, especially as regards data analysis and permitting and enabling non-trivial computational work by outsiders.
