Optimising DESpec for Dark Energy science Will Saunders, DESpec workshop, College Station 9 th December 2012. Working on DESpec is wonderful. Because the design is science driven It’s the same science, for all of us! we even have a metric (FOM or maybe FOM/$)
An Echidna-style positioner for DESpec. Will Saunders 8 March 2011. General considerations. Must compete with BigBOSS - 5000 fibres, 10,000 x 1000s exposures over 500 nights over 14,000 deg 2 : 15M ELGs, 3M LRGs , 600k QSOs But DESpec has better telescope, seeing, weather, photometry
