inetic temperatures of these clouds need not to be the same for all clouds, in the contrary, rather large temperature variations are indicated. These facts make it necessary to reconsider the derivation of the formulae connecting the measured intensity of the 21-cm radiation with the density of the Hydrogen gas and the kinetic temperature. This paper intends to lead to an improvement for the solution of this problem.

The 6th edition of this classic text includes revised discussion of solar system radio astronomy, dust emission and radio supernovae, technical aspects of radio astronomy and receivers, new material on radiation from the early universe and new worked examples.
