Number of exposures and exposure times per OB are listed. Except in OB1 and OB9, exposures were taken with 1200 s both in the VIS and UVB arm. In the NIR, each of the exposures was split into two sub-integrations with half the exposure time (e.g. 1200 s VIS ⇒ 2×600 s NIR). Where not all exposures could be used for the reduction due to passing clouds, both the used and the total number are stated. Numbers in square brackets indicate the exposure times included in the NIR stack, if different from the VIS stack.
