Web15 aug. 2013 · The U.S. Department of Energy's Office of Scientific and Technical Information WebHectospec is a fiber-fed instrument on MMT with 300 fibers covering a 1 degree field of view (Fabricant et al. 2005). GC candidates were se- lected from the CFHT imaging described in §2.4. Pref- erence was given to candidates with g < 22, but with no color restrictions beyond the basic GC candidate cuts.
