Injected box test of pure Gaussian noise with σ = 2.32 ppt and n = 33256 data points. Right column: CDF of DSP for various injected box depths δ. Vertical bars show the observed value (6^th column of Table B.1 in row 4). Left column: PDF of the phase difference between the test box center and the calculated secondary eclipse center from the bin model for the same box depths as shown in the corresponding panel on the right. The bin width is the total transit duration, i.e., in phase units ϵ = 0.030.
