Time-delay estimate of HE 0047−1756. Each point corresponds to the results of PyCS applied on a different data set. The “PyCS-sum” (in black) and the “PyCS-mult” (in shaded gray) are two possible combinations of the results of this work with the C2 and ECAM results measured in Millon et al. (2020). “PyCS-mult” corresponds to the multiplication of the probability distribution, whereas “PyCS-sum” is their marginalization.
