public class NightOptimalMerit
extends AbstractMerit

A merit calculating its gain such that a single observation in a given night should be performed, if combined with an appropriately high ranked constant merit. We consider cases, where the target is still on the rise and enough time remains (governed by the stated solar height or the remaining target time) for an execution of the target to be non-optimal, if the target will get higher up in the near future. In this case we return zero, in all other cases 1.
