Member Function Documentation

◆ add_extension()

void Pulsar::Integration::add_extension ( Extension * ext )

virtual

Add an Extension to the Integration instance.

The derived class must ensure that only one instance of the Extension type is stored.

Returns: On successful addition, this method should return the pointer to the Extension, equal to the extension argument. If the Extension is not supported, this method should return a null pointer.

Derived classes need only define this method, as the non-const version implemented by the Integration base class simply calls this method.

Referenced by Pulsar::ColdPlasma< DispersionDelay, Dedisperse >::execute1(), Pulsar::ASPArchive::load_Integration(), Pulsar::FITSArchive::load_Plasma(), Pulsar::FITSArchive::load_Pointing(), Pulsar::FITSArchive::load_SpectralKurtosis(), and Pulsar::TimeIntegrate::transform().

◆ cal_levels()

	)		const

Returns the mean hi/lo and variance of the mean hi/lo of every profile.

Returns the mean (and variance of the mean) off the on and off pulse cal levels.

Referenced by Pulsar::DynamicCalSpectrumPlot::get_plot_array().

◆ combine()

void Pulsar::Integration::combine ( const Integration * from )

protected

Combine from into this.

Users of this method should be aware that it does not keep full track of all the parameters of an Integration. It is designed to be used for low level arithmetic style addition only, not fully consistent combination. The supplied tscrunch routines should be used for such purposes.

This method is provided for experimental purposes and should not be used lightly. If the time spans of the two combined subints are not contiguous, several parameters in the result are no longer meaningful. Also, there is no way of knowing whether the profiles are aligned in phase. Developers who use this operator should perform the necessary rotations at the archive level (where the polyco resides) before summing the data in the Integrations.

Return an orphaned pscrunched dedispersed fscrunched clone of self.

This method is primarily designed for use by the Integration::find_* methods. After calling fscrunch, the resulting Profile may have a different centre frequency than that of the Integration.
