FF BX - Fourier Filter - Bar, kx direction

(1/10/94)

PURPOSE

Removes coefficients along the kx-direction of the Fourier transform.

SEE ALSO

FF [Fourier filter]
FF B [Fourier filter - bar, ky direction]

USAGE

.OPERATION: FF BX

.INPUT FILE: FOU001
[Enter name of input file containing Fourier transform. Note that this file will be overwritten by the filtered file.]

.WIDTH OF BAR (KY-BAR,KX-BAR): 3,4
[Enter width, in Fourier units, of the strip centered on the ky-axis that is to be removed from the Fourier transform.]

NOTES

  1. Operation 'FF BX' was developed to remove residual noise in the EIKONIX scan data due to insufficient normalization of the diode array.
