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.

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.
