Packages that use Epoch

net.grelf.astro

This package contains Java classes for astronomical applications.

Uses of Epoch in net.grelf.astro

Fields in net.grelf.astro declared as Epoch

protected Epoch	StarChartLoader.equinox
static Epoch	Epoch.J2000

Methods in net.grelf.astro that return Epoch

Epoch	Epoch.clone() Returns a new Epoch object with the same data.
Epoch	SkyPoint.getEpoch() Deprecated.
Epoch	SkyPoint.getEquinox()
Epoch	StarChartLoader.getEquinox()

Methods in net.grelf.astro with parameters of type Epoch

void	Star.changeEpoch(Epoch newEquinox, JulianDate newEpoch) This adjusts the fields of the current object to the given new equinox (eg, J2000) and epoch (eg, JD now) by first applying proper motion for the new epoch and then calling SkyPoint.changeEpoch (equinox) on the resulting position.
void	SkyPoint.changeEquinox(Epoch newEquinox) This adjusts the fields of the current object to the given new epoch, high accuracy version.
void	SkyPoint.changeEquinoxLowAccuracy(Epoch newEquinox) This adjusts the fields of the current object to the given new equinox, low accuracy version.
protected SkyPoint	Star.measureTargetBlob(java.util.List<BlobMeas> refBlobs, BlobMeas targetMeas, Epoch epoch, MeasuredValue degreesPerPixel)
protected SkyPoint	Star.measureTargetBlob2(java.util.List<BlobMeas> refBlobs, BlobMeas targetMeas, Epoch epoch, MeasuredValue degreesPerPixel)

Constructors in net.grelf.astro with parameters of type Epoch

SkyPoint(RA ra, Dec dec, Epoch equinox)

Star(java.lang.String commonId, java.lang.String hipparcosId, java.lang.String tychoId, RA ra, Dec dec, Epoch epoch, Magnitude magnitude, Variability variability)
Generally two of the ids passed in will be expected to be null; they may get set after construction.

Star(java.lang.String commonId, java.lang.String hipparcosId, java.lang.String tychoId, RA ra, Dec dec, Epoch epoch, Magnitude magnitude, Variability variability, double xdd, double zdd)
Generally two of the ids passed in will be expected to be null.

Star(java.lang.String commonId, java.lang.String hipparcosId, java.lang.String tychoId, RA ra, Dec dec, Epoch epoch, Magnitude magnitude, Variability variability, ProperMotion pm)
Generally two of the ids passed in will be expected to be null; they may get set after construction.

Star(java.lang.String commonId, java.lang.String hipparcosId, java.lang.String tychoId, RA ra, Dec dec, Epoch epoch, Magnitude magnitude, Variability variability, ProperMotion pm, double xdd, double zdd)
Generally two of the ids passed in will be expected to be null.

StarChart(java.lang.String title, RA ra, Dec dec, Epoch equinox, JulianDate epoch, double fieldWidthDegrees, boolean showVariables, boolean showChartCentre, StarChartSource source)
If the title is null then one is constructed from the data (so many degrees around position).

StarChart(java.lang.String title, RA ra, Dec dec, Epoch equinox, JulianDate epoch, double fieldWidthDegrees, StarChartSource source)
Use this constructor if you always want to mark variable stars and the chart centre.
