The Offset Correction is a special normalization to a user defined position
on the x-axis. All data objects in the current data view will be scaled
to match a user defined position in the current active object.
Use the Offset Correction command
from the Mathematics menu
or select the Offset Correction operation directly from the Mathematics
tab to perform this operation. The following options will be displayed
in the Mathematics Tab:
The following algorithms are available for performing an offset correction:
- All objects in the current data view will be shifted
to the current intensity at the selected x-axis position of the active
data object. Consequently, the intensities of all other objects will be
increased/decreased by intensity difference at the selected position.
- All objects in the current data view will be scaled to
the current intensity at the selected x-axis position of the active data
object. Consequently the active object will remain unchanged and the intensities
of all other objects will be multiplied by the factor ActiveSpectrumIntensity[x]
Selecting the offset correction function shows a vertical line indicating
the position on the x-axis, where correction takes place. After performing
a ShiftToOffset calculation, all spectra will be shifted to match the
intensity of the active spectrum at the given position. The user may also
enter a destination intensity value to which the spectra will be matched.
The result looks like this:
