Top: BIC values as a function of trial mid-transit times. Color-coded are the number of detrending components for each of the detrending models (submodels). Darker colors correspond to a smaller number of detrending components. Bottom: same BIC values, but now as a function of the detrending model, DM. Numbers on the abscissa are in agreement with the labels on Eq. (5). Color-coded are the trial T₀ ’s. According tothe color scale, red points correspond to T₀ = 0.
