public class SVStar

extends SVSkyObject

This is a general purpose star object that can store any and all information of interest from a star catalog, as well as due calcuations about it self for apparent location at a particular place on earth, at a particular time.

              double CatEpoch)

Constructor

Parameters:

theRA_Cat - Catalog Right Ascention

theMu_RA - Catalog proper motion of right ascention in [angle chang/cy]

theDec_Cat - Catalog declenation

theMu_Dec - Catalog proper motion of declination in [angle change/cy]

theMag - Magnitude of star

theName - Name of star

CatEquinox - Equinox of RA/Dec in catalog (i.e. B1950 or J2000)

CatEpoch - Epoch of RA/Dec in catalog (i.e. B1950 or J2000)

Method Detail

getRAFixProperMotion

public double getRAFixProperMotion()

Returns:

The right ascention with corrections for propermotion applied based on the "current" epoch.

getDecFixProperMotion

public double getDecFixProperMotion()

Returns:

The declination with corrections for propermotion applied based on the "current" epoch.

getApparentAzAlt
