Peak pattern atlas

The forest and the trees

Given our ability to generate theoretical XRF spectra we can now build an atlas of spectral peak patterns for different chemical elements. In the following we will ignore the exotic Lanthanides and Actinides and further limit our attention to what I call the Elements Of Interest. To plot the periodic table instantiate the PeriodicTable class and run the .plot() method. The edges of pre-selected elements of interest (to me) are colored red.

from moseley import PeriodicTable, PeakPatternAtlas

table = PeriodicTable()
table.plot_table();

We are now in a position to compute our atlas of elemental XRF peak patterns…

ppa = PeakPatternAtlas()

ax = ppa.plot_atlas()
ax.set_ylabel('Elements (alpha sorted)');
