public class MidnightMerit
extends AbstractMerit

A merit that is peaks around the true midnight, i.e. if tau of sun is 180ˆ. It centers at that time with fwhm defined with KEY_SHARP. If tau is further of than KEY_RISE, zero is returned.

Constructor Detail

MidnightMerit

public MidnightMerit(Map prop)

Constructs a new window merit using only default weights and impacts. The proper way to create a window merit is using the AbstractMerit.createMerit(java.util.Map<java.lang.String, java.lang.String>) method. This create method also takes care of proper parameter overloading.

Method Detail

getMerit

public double getMerit(GlobalGrouping set,
                       Appointable target,
                       Collection ignore,
                       long duration)

Calculates the window merit stemming from the target definition.

Parameters:

set - Current observing conditions.

target - The actual target.

ignore - All targets, observable or not.

duration - The relevant time span in ms.
