Notes. The seeing is the value measured by the differential image motion monitor (DIMM) at 0.5 μm. DIT (detector integration time) refers to the single exposure time, NDIT (Number of Detector InTegrations) to the number of frames in a single data cube, N_exp to the number of data cubes, and ΔPA to the amplitude of the parallactic rotation.

This sequence was a test and we only used the coronagraphic images with the satellite spots for measuring the astrometry of the companion.
