Comparison of literature spot coverage fractions to our results. The Sun is shown with the “⊙” symbol; HAT-P-11 is shown with the large diamond. The most significant outlier is HD 134319 (IU Dra), for which we measure very small spot coverage (see Section 3.2.8). The scatter about the one-to-one correspondence line represents a combination of (1) intrinsic variability in the spotted surface area of each star and (2) underestimated uncertainties in one or both measurements.
