Fig. 7, panel (b)

Uncertainty $\Delta b_\perp$ ($\mu$T) of the inferred transverse field component against the number of data traces $N$, log-log. Markers are the mean posterior width over 1000 repetitions for each $N$, with the standard deviation across them drawn as a band where the print has error bars; the dotted line is the $\sim 1/\sqrt{N}$ scaling.
