Now, at least it does what the documentation says it does.

It calculates the partiality for each reflection and multiplies it by the fully integrated intensity to produce a partial intensity. The fully integrated intensities can be taken from a file you provide (see below), otherwise they will be randomly generated (by taking the absolute value of a Gaussian random number, mean zero and standard deviation 1000). All the partial intensities for the orientation are multiplied by an overall scaling factor, which is randomly generated with a Gaussian distribution with mean 1 and standard deviation 0.3. The partial intensities are written to the output stream, and the process repeated for as many different orientations as you ask for (see below, default: 2). -.P -See -.BR "man crystfel_geometry" -for information about CrystFEL geometry description files. +Set the incident radiation wavelength and bandwidth in the geometry file.
