You can now use measured sheet resistance values for analysis of traverse data. This can significantly stabilize the fitting of silver based glass coatings, in particular if you fit both silver thickness and quality (using the Drude model damping constant).
In order to use sheet resistance values, you need to update VAAT_spectrum_scanner.exe, bright_eye_traverse.exe and the OLE server code.exe. All program files must be generated on August 29, 2014, or later.

A new OLE command has been implemented: import_measured_sheet_resistance(a_value : float)
Use this command to pass a measured sheet resistance value to CODE. This is useful if you would like to use this value in a fit, in addition to measured optical spectra.
The value is passed to the list of integral quantities. The list must contain an object of type ‘Sheet resistance’ with the name ‘Sheet resistance fit’ – only in this case the value is passed as target value.
In order to use this value you must set the option ‘optimize’ of the sheet resistance object. If you want to fit both spectra and sheet resistance, you must set the global fit option ‘Combine fit deviation of spectra and integral quantities’.
