Distribution of TESS single transits visible from Paranal for an arbitrary year. The data has been binned into weeks. The different colours correspond to different amount of the transit being visible. Colours blue, green, yellow and red corresponded to transits of the types 1, 2, 3 and 4 as described in the text. Additionally, the thick black line indicates the length of a Paranal night in hours. The HJD value is offset to run from 0–365 to cover 1 yr of observations.
