CFFT2 Class

2-D Fast Fourier Transforms These methods now work with an IMG object, instead of creating their own FFT2 object.

The CFFT2 type exposes the following members.

Methods

	Name	Description
	CrossCorrelationPG	Calculate the cross-correlation of two transform pagers: The complex conjugate of (r, i) items in the first pager are multiplied by the second pager (r, i) values.
	Fft2In	FFT2 transform
	FilterPG	Apply 2D FFT filters to data in pager
	FilterResponse	Calculates response for filter(s) defined in control file. Not specific to 2D.
	Flt	FFT2 filter
	FltInv	FFT2 filter and inverse
	PowSpc	FFT2 transform power spectrum
	RadSpc	FFT2 transform Radially averaged power spectrum
	RadSpc1	FFT2 transform Radially averaged power spectrum for one IMG
	RadSpc2	FFT2 transform Radially averaged power spectrum for two IMGs
	RadSpcAlt	FFT2 transform Radially averaged power spectrum - log before average and no normalization
	TdXdY	FFT2 filter (calculate T from the derivatives Tx and Ty)
	TransPG	Apply 2D FFT transform to data in pager
