Class DistanceEstimator

java.lang.Object

gaia.cu9.tools.parallax.DistanceEstimator

public class DistanceEstimator
extends Object

This class calculates the distance estimation for a given star. In the constructor, the estimator of the PDF of the distance to be used is specified, and can be reused for several stars. Several parameters controlling how the estimation should be done can be passed through an optional Map<String, String>
