+Description
+-----------
+
+This algorithm calculates the absorption factors, required for the Paalman Pings method of absorption corrections, using a Monte Carlo procedure. Currently only the acc and ass factors are calculated.
+
+CalculateMonteCarloAbsorption subsequently calls the :ref:`algm-SimpleShapeMonteCarloAbsorption` algorithm for the calculation of each absorption factor.
+
+There are three existing Shape Options: *Flat Plate*, *Annulus* and *Cylinder*. Each shape is defined by a different set of geometric parameters.
+
+Flat Plate parameters: *SampleThickness* and *SampleWidth* for the Sample, *ContainerFrontThickness* and *ContainerBackThickness* for the container.
+Annulus parameters: *SampleInnerRadius* and *SampleOuterRadius* for the Sample, *ContainerInnerRadius* and *ContainerOuterRadius* for the container.
+Cylinder parameters: *SampleRadius* for the sample, *ContainerInnerRadius* and *ContainerOuterRadius* for the container.
+
+The location and orientation of the sample can be defined with *SampleCenter* and *SampleAngle*.
