USAGE

.OPERATION: PJ 3E

.THREED FILE: PIC001
[Enter the name of the file whose projection is to be computed.]

.PROJECTION SAMPLE DIM.: 110,78
[Enter the X dimension and (optional) Y dimension for the projection file equal to, or smaller than, the volume sidelength. If Y dimension = 0 then the Y dimension is chosen such that the X/Y ratio in the projection is the same as in the volume. Arbitrary dimensions can be used.]

.OUTPUT FILE: PRJ001
[Enter the name of the file where the projection is to be stored.]

ANGULAR DEFINITIONS: r^= D(psi(around z^)* D(-theta(around y^)* D(phi(around z))*r

.AZIMUTH ANGLE (PHI): 45.5
[Enter the azimuth angle, in degrees.]

.TILT ANGLE (THETA): -30.0
[Enter the tilt angle, in degrees.]

.THIRD ANGLE (PSI=rot. in proj. plane): 0
[Enter the angle, in degrees.]

[For this example, the projection of PIC001 with PHI equal to 45.5 and THETA equal to -30.0 is computed and stored in PRJ001.]
