Description

A rectangular x-ray source that samples ray intensity from an image, and
deflects the emitted ray to reflect having been emitted from the sampled part
of the extended source. Rays that are sampled from the same point on the image
are collimated, but can be emitted from anywhere on the rectangular source.
The image should be provided as a 2D-ascii table, whose header includes the
following entries:

w_pixels and h_pixels: The width and height of the image in pixels
x_ref and y_ref: x and y reference values of the FITS image
r_max: The maximum distance from the point (x_ref, y_ref) to any corner of the image
iCD11, iCD12, iCD21 and iCD22: The values of the FITS image's CD matrix

Input parameters

Parameters in boldface are required; the others are optional.
