Representations of the evolution of the biases and signals with field rotation and time based on the observations of the single star HD 211976. Top: correlation between pairs of the kernel-phase vectors evolving with their temporal separation. Bottom: series ADK signal for different target separations. The colored regions represent the standard deviation of the realizations in our sample, therefore, it is not relevant for the largest field rotation samples that only have one realization. The contrast for the binary signals are adjusted to provide signals of similar amplitudes.
