Port 0 is the required input port for the MRS data to be phased. Port 1 is the optional input port for a phase map of values to apply

void FirstOrderPhase	(	float	phi1,
		int	pivotPoint,
		vtkFloatArray *	spectrum
	)

static

Applies first order phase to the complex spectrum. inputs: phi0, phase in radians phi1, phase in radians (pivot at center of spectrum (assume 0Hz spectrum

float GetLinearPhase ( )

This returns the current data phase, which may differ from the value input to SetLinearPhase until the data has been updated.

float GetPhase0 ( )

This returns the current data phase, which may differ from the value input to SetPhase0 until the data has been updated.
