.FOURIER FILE: FOU001
[Enter the name of the Fourier file.]
.WINDOW SIZES (SEARCH,FILT): 7,5
[Enter the dimensions of square windows to be used in the
search for maxima and filtration (2nd not presently
used).]
.LATTICE INDICES (H,K): 1,0
[Enter the lattices indices of first reflection.]
.FOURIER POSITIONS (KX,KY): 42,27
[Enter the approximate kx and ky positions (relative to
0.0 at center of Fourier transform and associated power
spectrum) of the reflection associated with the above
indices. The exact position of the maximum within the
search window is determined and returned. Note: axes are
transposed going from real to Fourier space. Real space:
+x is to the right, +y is down. Fourier space: +kx is
down, +ky is to the right.]
.LATTICE INDICES (H,K): 2,1
[Enter the lattice indices of the second reflection.]
.FOURIER POSITION (KX,KY): 57,30
[Enter the approximate kx,ky position of the second
reflection.]

[...continues until (0,0) is entered for Lattice Indices.
A minimum of 2 reflections in linearly independent
positions are required. All reflections entered will be used
in a least square fit to extrapolate the reciprocal
lattice.]
.MAXIMUM RESOLUTION DISTANCE: 120
[Enter the radius of a circle in Fourier space within
which reflections on the indexed lattice are being
deterdetermined.]
[The initial and the refined lattice parameters will be listed along with x and y components of each. A list of the reflections found, and their energies, is recorded in the RESULTS file.]
.FILTER FILE: FIL001
[Enter the name of the file that will contain the
coordinates of the refined lattice for use in filtration.
See 'GF' and 'RD' for details.]
