Constructor Detail

JTrackingFrequencies

public JTrackingFrequencies(ResourceSupplying prop)

Constructs a new data canvas that goes into listening state on JDataCanvas.init().

Method Detail

setComposedProperties

public void setComposedProperties(ResourceSupplying prop)

Defaults the repository name and the sensors to monitor.

Specified by:

setComposedProperties in interface ResourceAware

Overrides:

setComposedProperties in class JDataCanvas

setTimeGap

public void setTimeGap(long ms)

Sets the time intervall in which the data points were taken.

setExposureTime

public void setExposureTime(long ms)

Sets the exposure time on the guider system in ms. The time is needed for the seeing power spectrum.

setSeeing

public void setSeeing(double arcsec)

Sets the seeing estimate as deduced from the guider system. This seeing measure is adjusted to a 'true' seeing by multiplication with KEY_SEEINGFACTOR.

setWind

public void setWind(double mpers)

Sets the measured maximum wind speed. For the seeing power spectrum, the average wind speed in the atmosphere column is needed. This can only be estimated via a multiplication of the wind speed with KEY_WINDFACTOR.

setOffsetMeasures

public List setOffsetMeasures(String name,
                              VectorG data)

Sets the data set. Each pointin the provided VectorG should correspond to an arcsec offset in either the azimuth or the altitude axis.

addSeeingToPlot

public void addSeeingToPlot(int length)

Adds the seeing data to the plot.

getPower

private static VectorG getPower(VectorG data)

Zero-pads the data to both sides if necessary and does a simple power spectrum on it. Returns the power spectrum as an VectorG of half the size of the zero-padded data, lowest frequency at index zero. Uses a PowerSpectrum#WelchWindow.

convertToPlot

private List<VectorG> convertToPlot(VectorG power)

Adds a power-vector to this graph, on-the-fly transforming index in the vector to frequency in Hertz.

Returns:

A list of Vector2D, x is frequency, y is power.
