–Note: A summary of epochs is given in Tab. 2. Note that the uncertainties here do not contain systematics such as magnification uncertainties or the systematic scatter between epochs. The filters listed here are only those used in section 4, i.e., the bands that have coverage in at least one epoch in 2022 and 2023 each. The NIRCam epoch 5, listed in Tab. 2, only contains medium bands that are not observed in any other epoch and is therefore not used further in section 4.
