\label{fig:survey} Uncertainties of trapezoidal transit parameters for representative observing cases as functions of exposure time \(t_{exp}\), as predicted by the binned trapezoidal light curve model. For planets on orbits of 1 day (red curves), 10 days (blue curves), and 100 days (black curves), we show the expected uncertainties for total survey lengths of 1 month (solid curves), 3 months (dashed curves), and 4 years (dotted curves). We assume nominal parameter values \(b = 0.2\), \(e = 0.16\), and \(r = 0.1\), to remain consistent with the figures above; we scale the photometric uncertainty such that a Kepler 30-minute exposure corresponds to \(\sigma = 5 \times 10^{-5}\). \(\Gamma_{eff}\) is given by Equation \ref{eqn:gamma_eff} when \(T_{tot} > P_{orb}\); otherwise, \(\Gamma_{eff} = 1/t_{exp}\).
