The first three scans trace a path that would form a radial cut if projected on to the K-L, H-L or H-K planes at the specified angle in degrees from the positive K, H or H axes, respectively.
start_radius
and
finish_radius
specify the radial distance from the origin.
The unscanned coordinate will be reevaluated at each point according
to the optional expression in the last argument, which can be a function
of the other coordinates, for example,
H=L/300. Otherwise, the unscanned
coordinate will remain constant.
The second three scans differ only in that they trace out a circular arc in the projected plane at the radius given by the first argument.
start_angle
and
finish_angle
are the endpoints in degrees of the arc of the scan.
