Examples of transfer function calibration for the visibility (left) and the closure phase (right). Only a single spectral channel and a single baseline (triplet for the closure phase) is represented. The black squares are the transfer function estimates made on calibration stars extracted from the Mérand et al. (2005) catalog. The solid and dashed lines represent the interpolation of the transfer function, with its uncertainty. The colored circles are the observations of scientific targets.
