Table A.1:

Observation log for the AGN of the snapshot survey, including the detector integration times (DIT), the number of frames (NDIT) for the fringe tracks and photometries as well as the lengths (BL) and position angles (PA) of the projected baselines. The times, ambient values and baseline properties relate to the start of the fringe track.
