seismicVeto
Class VetoProcess.ChannelDetector

java.lang.Object
  seismicVeto.VetoProcess.ChannelDetector

Enclosing class:

VetoProcess

 class VetoProcess.ChannelDetector
extends java.lang.Object

Since the detector may be running on several channels, make a sub class for the actual detector code so that multiple instances may be created.

Constructor Detail

VetoProcess.ChannelDetector

public VetoProcess.ChannelDetector(int channel)

Method Detail

pamStart

public void pamStart()

newData

public void newData(PamObservable o,
                    FFTDataUnit arg)

Performs the same function as newData in the outer class, but this time it should only ever get called with data for a single channel. For the first few calls, it just updates the background by taking a straight mean of the energy values. After that it calculates a decaying average of the background.

Parameters:

o -

arg -

fillWaveData

protected void fillWaveData(double[] data)

clearWaveData

protected void clearWaveData(double[] data)

prepareRandomWaveData

private double[][] prepareRandomWaveData(int nSamples)

generate a number of random samples of data which follow a particular spectral shape. These will be stitched together in random order to make a longer wave sample in the veto

Parameters:

nSamples -

sampleLength -

energySum

private double energySum(Complex[] fftData,
                         int bin1,
                         int bin2)

startDetection

private void startDetection(FFTDataUnit dataUnit,
                            double energy)

continueDetection

private void continueDetection(FFTDataUnit dataUnit,
                               double energy)

endDetection

private void endDetection()

getRunningBackground

public double[] getRunningBackground()
