In case the defined THEORY is <strong>not</strong> ready to run on the accelerator, <code>musrfit</code> will fall back to the default behaviour. In the <a class="foswikiCurrentTopicLink" href="#TheoryTable">THEORY table</a> all the functions which are currently <strong>not</strong> GPU ready are marked by <img class='smily' src='../pub/Main/SmiliesPluginPSI/no.gif' alt='no' title='no' /> in the reference column.

The Fourier transform is done and the results are plotted within <code>musrview</code> —as input data the actual data shown in <code>musrview</code> is used. In the FOURIER block of the msr file all necessary parameters for calculating and presenting the Fourier transform of the data specified in the <a class="foswikiCurrentTopicLink" href="#ThePlotBlock">PLOT block</a> is given. If the FOURIER block is not present in the msr file, either the parameters set in the <a class="foswikiCurrentTopicLink" href="#MusrfitStartupXml">XML startup file</a> or the system defaults are taken when the Fourier transform is performed. The block starts with the FOURIER keyword and may contain the following entries on the successive lines: <dl>
