 +  - The index of the layer. This index is used to reference its parameters in the script, e.g thickness[2] for the thickness value of layer 2.
 +  - Thickness of the layer in Ångström
 +  - Filename of the optical constants database files without ending (here Co.db, Cu.db, and vacuum.db). Files have to be in the same directory as the .all file.
 +  - Optical constant delta, for the given energy (either from .db file or entered manually)
 +  - Optical constant beta, same as delta
 +  - Sigma, RMS roughness in Å between the layer and the one above!
 +  - Magnetic delta, magneto optical constant (see remarks below)
 +  - Magnetic beta, see magnetic delta
 +
 +The example system is a multilayer consisting of 6x[ Co (10Å) / Cu (60Å)] on a Cu substrate. The optical constants provided correspond to a X-ray energy of 900eV and the .db filenames to the files shipped with this version of ReMagX (check the installation directory).
 +Remarks:
 +Delta (δ) and Beta (β) are the optical constants (dispersive and absorptive part) of the material according to the standard notation of a complex index of refraction: 𝑁=1−(𝛿+𝑖β).
 +Sigma (σ) is the RMS roughness according to standard notation in surface science.
 +Magnetic delta (δm) and beta (βm) are the variation of the optical constants due to magnetism. NOTE: the values are added/subtracted to the normal optical constants!

 +  * Select a cell on the “layer input table” by left mouse click.
 +  * Change a parameter by double clicking it.
 +  * Select a cell and right click for additional options.
 +
 +----
 +The additional options available from the dropdown menu are:
 +
 +^ Fit (On/Off)      | On/Off switch for selecting this parameter for fitting |
 +^ Show Delta and Beta spectrum   | plots δ & β from the .db file. The script can alter this values |
 +^ Show Deltam and Betam spectrum   | plots δm & βm from the .m file The script can alter this values |
 +^ Get optical constants from database  | Loads the optical constants from .db .m and .e files for all layers and put them into the table for the current energy |
 +^ Properties | Provide additional information about the layer |
