Method Details

getNoiseFloor

public static double getNoiseFloor(double[] waveform)

getMaxTime

public static double[] getMaxTime(TimeSeries waveform,
 TimeT originTime)

This method mimics the getMaxTime method of SacSeismogram, which is NOT purely the same as the methods in the TimeSeries chain. Trying to not use SacSeismogram directly as it will be moving out of Core > 1.1 and will introduce an extra dependency.

Parameters:

waveform -

originTime -

Returns:

double[] where 0 is the origin time shifted by the waveform's beginTime + maxTime and 1 is the amplitude value recorded at the original maxTime

doublesToFloats

public static float[] doublesToFloats(double[] x)

floatsToDoubles

public static double[] floatsToDoubles(float[] x)

isValidWaveform

public static boolean isValidWaveform(Waveform w)

cutSeismograms

public static boolean cutSeismograms(TimeSeries a,
 TimeSeries b,
 TimeT startTime,
 TimeT endTime)
