Parameters

	Name	Type	Identifier	Description	Constraints
Input	Grid	grid, input	`GRID`	-	-
Output	Fourier Transformation	grid collection, output	`DFT`	-	-
Output	Fourier Transformation	data object Grids, output, optional	`DFT_OPT`	-	-
Options	Grid System	grid system	`PARAMETERS_GRID_SYSTEM`	-	-
	Centered	boolean	`CENTERED`	-	Default: 1
	Output Size	choice	`SIZE`	The optimal size for the discrete Fourier transformation might differ from that of the input grid.	Available Choices: [0] same as input grid [1] optimal DFT size Default: 0
