Method Detail

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent ae)

Specified by:

actionPerformed in interface java.awt.event.ActionListener

backscatterFraction

public double backscatterFraction()

backscatterFraction - Returns the fraction of electrons which strike the sample that scatter back into the negative-z direction.

Returns:

double

forwardscatterFraction

public double forwardscatterFraction()

backscatterFraction - Returns the fraction of electrons which strike the sample that scatter forwards into the positive-z direction.

Returns:

double

energyBin

public double energyBin(int bin)

elevationHistogram

public int[] elevationHistogram()

elevationHistogram - Returns a histogram of the backscattered and forward scattered electrons as a function of elevation. The beam is at bin zero. The final bin is contains 180 degrees. The function elevationAngle returns the mapping between bin and angle.

Returns:

int[]

elevationAngle

public double elevationAngle(int bin)

elevationAngle - Maps bin numbers into elevation angles.

Parameters:

bin - int - The bin number

Returns:

double - The angle in radians

azimuthalHistogram

public int[] azimuthalHistogram()

azimuthalHistogram - Returns a histogram of the backscattered and forward scattered electrons as a function of the azimuthal angle. Bin zero is at the x-axis as is the last bin.

Returns:

int[]

azimuthalAngle

public double azimuthalAngle(int bin)

azimuthalAngle - Maps bin number in the azimuthal angle into angles in radians.

Parameters:

bin - int

Returns:

double

dump

public void dump(java.io.OutputStream os)
