All objects of that type up to recombination epoch may be measured if they exist there.
Project specification is under discussion now.
It will include the theory of the proccesses in this range and a discussion of the possible observational aspects of the problems and suggested specification for the next century NG instrumentation. The physics of the Recombination of the Universe may traced in this way and primordial Big Bang Chemistry may be checked as well. A Cosmic Rosetta Stone Douglas Scott's CMB pages and CMB FAQ .
