 11. ctmodel - CTA counts cube modelling
 ---------------------------------------
-None
+The ctmodel tool can now be used for stacked analysis from the command line.
+It directly makes use of the cube response to compute the model without using
+the original IRF information. This makes generation of model cubes substantially
+faster. The old method of accessing the IRF response for model computation is
+still possible.
