Exporting peak profiles

If you would like to plot the spectrum and peak fitting solution in another software package, you can export the spectrum and peak profiles using the ‘Peak fitting→Export peak profiles...’ menu option, as shown below:

The ‘Peak fitting→Export peak profiles...’ menu option.

The file that is exported is a comma separated text file, and example of which is shown below:

This particular file shows the peak profiles for three peaks fitted to a boron nitride spectrum. After the header, the columns are:

The first column, labelled ‘Channel’, contains the channel ordinal, starting at 0.
The second column contains the x-axis coordinate of the channel, the units of which are given in the column header (e.g. ‘eV’, ‘nm’).
The third column gives the intensity values of the original spectrum, with the name of the spectrum given in the column header (e.g. ‘BN’).
The fourth column, labelled ‘Sum’, gives the channel-by-channel sum of all the fitted peak profiles.
The fifth and subsequent columns contain the intensities of each peak in the peak table, with the name of the peak given in the column header (e.g. ‘3.0398eV’, ‘2.3898 eV’ and ‘3.6235 eV’).

The peak profile file may be readily imported into spreadsheet packages and plotted, as shown below:
