This tab is designed for the user to transform pre-loaded data into the frequency domain. At present there are two methods available, which the user can switch between by using the drop-down menu at the top of the tab.
In this mode the interface displays two tables, FFT and Advanced options. The FFT table contains all of the information required to produce a forward FFT. The Advanced Options table contains the information for adding padding and apodization functions to the data.
If the workspace contains the word PhaseQuad it will run the PhaseQuad algorithm on the selected run when Calculate is pressed. If no phase table is available then
the one will be generated and the result will be stored as PhaseTable.
The Calculate button will execute the Padding and Apodization and then FFT algorithms. The output workspace will be added to
appropriate grouped workspace.
The maximum entropy method can be used to calculate the frequency domain spectrum. This option uses the MuonMaxent algorithm to calculate the frequency spectrum. The MaxEnt Property table contains
the basic quantitites used during the calculation. If the Use Phase Table checkbox is set to true, then an input phase table will be used for the initial phase values. The phase table can be constructed or another phase table can be
selected from the drop down menu. When the Calculate MaxEnt button is pressed, CalMuonDetectorPhases is ran first if the phase table is to be Constructed.
The advanced property table contains variables for users that would like more control over the calculation.
For large calculations the interface can be slow, therefore the Calculate button is disabled until the current calculation is complete.
