Method Detail

setMajorAxisDiameter

public void setMajorAxisDiameter(double majorDiameter)

Sets the magnitude of the major axis diameter of this source.

Parameters:

majorDiameter -

setMinorAxisDiameter

public void setMinorAxisDiameter(double minorDiameter)

Sets the magnitude of the minor axis diameter of this source.

Parameters:

minorDiameter -

setPositionAngle

public void setPositionAngle(double decimalDegrees)

Sets the position angle of this source.

A source whose major axis runs north-south has a position angle of zero. Positive angles are measured eastward from north.

Parameters:

decimalDegrees -

getMajorAxisDiameter

public double getMajorAxisDiameter()

Description copied from class: SourceBrightness

Returns the diameter of the major axis of this source brightness in A.U.

Overrides:

getMajorAxisDiameter in class SourceBrightness

Returns:

the diameter of the major axis of this source brightness in A.U.

getMinorAxisDiameter

public double getMinorAxisDiameter()

Description copied from class: SourceBrightness

Returns the diameter of the minor axis of this source brightness in A.U.

Overrides:

getMinorAxisDiameter in class SourceBrightness

Returns:

the diameter of the minor axis of this source brightness in A.U.

getPositionAngle

public double getPositionAngle()

Description copied from class: SourceBrightness

Returns the position angle of this source brightness in degrees. The position angle is based on the major axis. A north-south orientation of the major axis is taken to be zero degrees. Positive angles are measured eastward from north.

Overrides:

getPositionAngle in class SourceBrightness

Returns:

the position angle of this source brightness in degrees.
