    839841cause the pattern to be simulated. When a pattern is first simulated, the
    840 observed pattern is set to the computed pattern. This means that it is actually
    841 possible to optimize any parameters that are selected to be refined. There is
    842 no reason to actually do this, so we will turn off optimization by setting the
    843 number of cycles to zero. Click on the Controls data tree entry and set the Max
