摘要: The Sunyaev-Zel'dovich (SZ) effect of galaxy clusters is characterized by three parameters: Compton parameter, electron temperature and cluster peculiar velocity. In the present study we consider problem extracting these parameters using multi-frequency SZ observations only. We show that there exists a parameter degeneracy which can be broken with an appropriate choice frequencies. As result discuss optimal observing frequencies from theoretical point view. Finally, analyze systematic errors (of order micro K) on measurement introduced finite bandwidths, suggest possible method reducing errors.
