Volumetric Dices for HMI (X-axis) and Solar Orbiter (SO in the figure) (Y-axis) for the study of Section 5. The HMI Dices are calculated for outputs from 13.5 days later than the Solar Orbiter data when activity has rotated to the near-side hemisphere, from which the HMI data are taken. The points represent data from May 1 to September 20, 2022, with a cadence of 5 days. The diagonal is shown in red for reference. The average volumetric Dices for HMI and Solar Orbiter are shown in the lower right corner.
