The figures above illustrate a baselinecorrection for a large range. The x-coordinates and baseline<br />
correction settings can be saved to a file with extension .bcf (baseline correction file) by clicking<br />
the “Save” button. Since only the x-coordinates will be saved, the same file can also be used to<br />
load a baseline for graphic files of the same product (but with different y-coordinates). After<br />
loading a bcf file, by clicking the “Load” button, the x-coordinates will be read from file and the<br />
points will be marked at the intersection with the selected spectrum.<br />

The default intensity unit is AD Counts. Since a 14-bit AD Converter is used in the <strong>Raman</strong> system,<br />
the y-axis range is 0 – 16383 AD Counts. The AD Counts unit does not include corrections for<br />
wavelength dependend sensitivity curves of CCD detector, grating and other optical components<br />
like mirrors. Without corrections, the AD Counts intensity ratio’s between peaks can be different<br />
from the peak intensity ratio’s in raman literature or databases.<br />
