public class BrightnessBasedPairMaker

extends Operation

The BrightnessBasedPairMaker is a class to make pairs among two lists of stars. From the brightest star to the faintest star, a star in the first list is getting paired with a star in the second list. If some stars are in the specified search area, the brightest one is selected as a counterpart. If all stars in the specified search area are too faint over the specified difference, it will not be paired with any one.

The (x,y) position and magnitude of stars in the both lists must be set properly. The two lists are sorted in the constructor.

Field Summary

protected double	acceptable_mag_difference The difference of magnitude to be accepted to paired with.
protected StarList	first_list The first list of stars.
protected PositionMap	first_map The map of the first list of stars.
protected java.util.Vector	pair_list The list of pairs.
protected double	search_radius The radius to search a counterpart.
protected StarList	second_list The second list of stars.
protected PositionMap	second_map The map of the second list of stars.

Constructor Detail

BrightnessBasedPairMaker

public BrightnessBasedPairMaker(StarList first_list,
                                StarList second_list)

Constructs a BrightnessBasedPairMaker with two lists of stars.

Parameters:

first_list - the first list of stars.

second_list - the second list of stars.

Method Detail

setSearchRadius

public void setSearchRadius(double radius)

Sets the radius to search a counterpart.

Parameters:

radius - the radius to search a counterpart.

setAcceptableMagnitudeDifference

public void setAcceptableMagnitudeDifference(double delta_mag)
