----- header of xyaup.pro extracted on: Fri May 31 15:31:05 2013 ----- Documentation for /scisoft/xop2.3/src_idl/sources/xyaup.pro ----- ============================== Xyaup ======================================= Xyaup is a widget based graphical interface to calculate spectra of a tapered undulator insertion devices. It interfaces the program YAUP 1.3.1 written by B. Boyanov (see Help/Yaup) DESCRIPTION OF THE CONTROLS IN THE MAIN WINDOW: File: XYaup input parameters: This option allows to save the current parameters to a file for later loading. It also allows to save the current parameters as defaults for being used when the application is initialized. In the last case, the file is named "application".xop (where "application " is the name of the current XOP application) and is written in the directory pointed by the XOP_DEFAULTS_DIR environment variable (which must be set). The parameter file is ASCII and can be read and edited with care. Yaup file: This option allows to load/write the current parameter and result files for further calculations. The used file formats are those used by YAUP. Therefore, they can be used to run YAUP without the interface or to import YAUP files created outside the XYAUP application. Write Files for XOP/Optics: Saves the current undulator spectrum in the SRCOMPE (flux) and SRCOMPW (Power) files to be used for the other XOP application from Optics menu. Quit and preserve files: Quits without cleaning current directory (i.e., preserving the created data files.) Quit: to exit from the program BField: from ASCII file: Yaup needs a file with tha magnetic field. This may be obtain from a user's file (column-formatted, containing three colums: z, B(z), and phi(z), where the z s are equidistant with step PERIOD/NPTS. See Help/Yaup for definitions of PERIOD and NPTS. There should be NPTS*NPER+1 lines in the ASCII file. from XBFIELD Preprocessor: calls XBFIELD, an interface for the program BFIELD distributed in the YAUP package. This program creates the magnetic field starting from the undulator oparameters. from Linear B field: Creates a magnetic field modulated with a straight line with the given B or K extrema. Set_Parameters: Set Parameters: to define the parameters for the calculation. The same result is obtained pressing the "Set Parameters" button in the main XYAUP window. Please refer to the information under the HELP button for a complete description of the parameters. After pressing the ACCEPT button, YAUP starts running. Set Defaults: Sets the default parameters. Show: Display results Plot B field: Plots the computed B field. Plot Trajectory: Plots the electron trajectory in the defined magnetic field. Show Trajectory Numerical Data: display the trajectory output file. Plot Results: Makes 2-D or 3-D plots of the results, depending on the mode and other defined parameters. Show Results Numerical Data: display the yaup result file. Help: Shows the YAUP help and the XYAUP help (this text).
