Actual computations

The sensitivity estimator computes the relationship between \ensuremath{\Delta t_\ensuremath{\mathrm{}}} and \ensuremath{\sigma_\ensuremath{\mathrm{Jy}}} with

\begin{displaymath}
\ensuremath{\sigma_\ensuremath{\mathrm{Jy}}} = \frac{\ensur...
...rm{pol}}}\,\ensuremath{\Delta t_\ensuremath{\mathrm{on}}}}},
\end{displaymath} (17)

where \ensuremath{T_\ensuremath{\mathrm{sys}}} is interpolated in frequency and airmass from the table, and the other parameters are defined by the observatory. It then computes the relationship between \ensuremath{\sigma_\ensuremath{\mathrm{K}}} and \ensuremath{\sigma_\ensuremath{\mathrm{Jy}}} with
\begin{displaymath}
\ensuremath{\sigma_\ensuremath{\mathrm{K}}} = \frac{\ensure...
...ensuremath{\mathrm{min}}}}{4\,\ln{2}\,\ensuremath{\lambda}^2}.
\end{displaymath} (18)
