.RANGE OF ALPHA FROM,TO (IN DEGREES): -90,85
[Enter angular range of transform]
.IN INCREMENTS OF: 5
[Enter angular sampling of Radon transform. The range and
increment is stored in the file header of the output file
in positions 54,55 and 56]
.OUTPUT FILE: RAD001
[Enter name of output file]
.X-DIMENSION OF OUTPUT: 40
[Enter the line dimension of the Radon transform]
.RADIUS OF CIRCULAR MASK:20
[Enter mask radius. Only image values within this mask
are used in the calculation of the Radon transform]
.CENTER OFFSET: 0,0
[The rotation center for the calculation of the Radon
transform is NSAM/2+1, NROW/2+1, but can be shifted
by entering an offset]
.(A)verage threshold,(T)hreshold/(L)ift/(N)one:
[Enter option: A: subtracts average and then sets
all negative values to 0. T: applies thresholds,
L: subtracts minmum from image, N: no changes of
input image ]
