$I_{v} = B_{v}(T_{b})$  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 subtended  by the receiver's diffraction pattern.\subsubsection{FIRST and synchrotron radiation - this section is incomplete}  FIRST survey detects synchrotron radiation at the lower radio frequencies in the meter and cm wavelength range as explained in section 1.2.  Given that the sensitivity limit of FIRST and our knowledge of radio source populations, we know this survey is dominated by the FR-I and FR-II sources described earlier. That is, radio jets that results from collimated electrons spiraling around magnetic field lines at relativistic speeds following acceleratio by a centered SMBH.
