Sketch of the distribution of datacubes in time. The rectangular sections indicate the extent of single datacubes, labelled by the time interval number “TI”. The numbers across the top are in minutes. Intervals start every 320 min, are 410.25 min long, and overlap by 90 min. We show only the datacubes close to the emergence time, t₀, indicated in red. In general, the EAR and CR extend both further forwards and backwards in time.
