Graphic of data taken and the split into two datasets for the 4-UT ESPRESSO transit. Time is indicated as phase on the x-axis, with the planetary orbit marked as a dashed arrow indicating the direction of movement in time across the stellar disc. The grey areas indicate when exposures where obtained during transit and how the data was split into one set centred around mid-transit (0.0, darker grey, mid-transit dataset) and the other comprising the rest of the exposures towards egress (from here called the egress dataset).
