$I_{v} = B_{v}(T_{b})$  where $B_{v}(T)$ is the Planck distribution brightness. The associated sensitivity is then proportional to the ratio of the system sensitivity and the solid angle substended by the receiver's diffraction pattern.  \subsubsection{FIRST and synchrotron radiation - this section is incomplete}
