Relativistic Corrections to the Sunyaev-Zel'dovich Effect for Clusters of Galaxies. V. Precision Analytic Fitting Formula for the Crossover Frequency Region

Naoki Itoh, Youhei Kawana, Satoshi Nozawa

We have succeeded in obtaining a precision analytic fitting formula for the exact numerical results of the relativistic corrections to the thermal Sunyaev-Zeldovich effect for clus…
