Caption: Figure 7.

Samples from the IRI used to build our sTEC priors. We sample the sTEC at each site toward random sky locations for targets and calibrators within the CHIME field of view and at random times. We then calculated the double-difference sTEC between the target and the calibrator and between the two telescope sites for each baseline. The figure shows histograms of these differential sTEC values for each baseline, as specified above each of the three panels. Finally, the fitted Student’s-t distribution that we use for the sTEC priors in our forecasts is over plotted, with the fit parameters listed in the legend.
