public class FlatMaximumTime
extends AbstractTargetValue
implements ExposureTimeMeasuring

The maximum exposure time allowed for flats is a filter function, because it basically defines when too much star light is visible in the flat. There is an upper cut that is related to the time scale of twilight darkening, as it is not useful to expose for an hour, if it is getting too dark too fast.
