Estimates of OmegaCAM observing overheads have been moved to this page , the general Paranal instrument overhead list..
Note regarding filters: It is recommended to avoid frequent ﬁlter changes within a single OB. Filter changes between different magazines take about one minute, while filter changes within the same magazine take about two minutes. The current distribution of the ﬁlters in the two magazines is optimized for a sequence u-g-r-i-z. Filter changes between subsequent OBs are supposed to be absorbed in the preset overhead.
