This routine saves all layer and screen settings as an ASCII file with the extension .lrc. The name of the file
may be chosen arbitrarily. Do not use any other extension than .lrc.
The *.lrc-file is an ASCII file which does NOT contain and reflectivity R(λ) as a function of wavelength (or
pixel) within the plot limits.

7.1.5

Save reference and dark

(internal mode and SCOUT mode)
This routine saves the current reference data to the file “NanoCalc\data\ref_files\name.ref” and/or to
“NanoCalc\data\ref_files\name_pixel.ref”. If the screen was switched to pixel resolution both of these files are
saved.
If the dark button was active also 1-2 dark files are saved
This function is easily accessible through function key F8.

7.1.6

Save as reference system

(internal mode only)
In Version NC_10nk there is an option to use “reference systems”. e.g. a glass reference with a backside
surface or even a stack of layers (e.g. native oxide). First you have to measure this reference system in the
normal way = with silicon as reference. Then press the button file/save as reference system. Then choose
this system as a new reference in EditStructure.

7.1.7

Load reference and dark

(internal mode and SCOUT mode)
This routine loads a reference from the directory “NanoCalc\data\ref_files”. If you choose to load a pixel
reference, both references will be loaded (eventually also dark files)
Which of these two files is displayed depends on the pixel or nanometers resolution.
This function is easily accessible through function key F9.

7.1.8

Load last measurement

(internal mode only)
This function is easily accessible through function key F11.

7.1.9

Load last saved file

(internal mode only)
This function is easily accessible through function key F12.

7.1.10

Import raw data

(internal mode and SCOUT mode)
You are asked for an import- directory. The imported values are displayed in blue (=similar to measured
values). The scale of the screen is not adjusted.

7.1.11

Export raw data

(internal mode and SCOUT mode)
If a curve was produced by simulation or measurement it may be exported as ASCC-file (“raw data”). This
file has a very simple structure: (lambda, value)
350,0.455
351,0.467
352,0.479
353,0.490
354,0.501
355,0.512
356,0.522
You are asked for a directory to save this file. Please use the default directory \RawData_Files\Reflectometry
