Top panel: Pie chart of single GES iDR5 exposures per instrumental setup. The part labelled “other” contains GIRAFFE setups HR3, HR5A, HR6, and HR15, as well as the U520 UVES setup. Bottom panel: distribution of sources per number of observations (single exposures) within GES iDR5. Even numbers are favoured because sources are generally observed in both HR10 and HR21. In the case of four observations, we generally have two consecutive observations in HR10 and in HR21, both close in time.
