Uncertainties in the antenna temperature estimate and the retrieved gain standard deviation as a function of antenna observation time for the same calibration structures shown in Figure 2 with a first-order autoregressive gain process. Notice how the Gaussian case analytical relationship between the uncertainties in the antenna temperature estimate and radiometer gain can be used to model the non-Gaussian radiometer gain as a Gaussian process with varying standard deviations as a function of antenna observation time and calibration structure.
