Wavelength
The spectrum shifts by the specified wavelength and compresses (<1) or stretches (>1) according to the
specified dispersion value. The reference point for compressing and stretching the data is set to the
smallest wavelength value of the spectrum. For an easy and precise comparison of overlaid spectra, it is
recommended that you adjust the wavelength scale as well as the underground and peak values of the
signal.
Signal
The spectrum shifts by the specified signal and compresses (<1) or stretches (>1) according to the
specified dispersion value.
Integral
Use the Integral dialog box to easily calculate integrals of lines and band structures. Two vertical, dashed
lines are displayed in the graph to represent the limits of the integral. These lines can be moved using the
mouse or the keyboard (L and R keys along with the arrow keys). The Integral dialog box is available for
Diagram windows and remains open until you close it.
