14.2 The Source_extended McXtrace Component
Release: McXtrace 1.4
A plane source emitting x-rays to emulate a distant extended source, such as a nebula or galaxy

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.
