Abstract
The importance of appropriate selection of the telescope beam size in measurements of the Zeldovich–Sunyaev effect is demonstrated by convolution of a Gaussian beam with the gas temperature and density profiles. Polytropic gas models characterized by parameters having values in the observationally-deduced (wide) range are considered. We discuss the relevance of this consideration to interpretation of recent measurements of the Zeldovich–Sunyaev effect.Keywords
