IB Chemistry: Convergence limits

In sub-topic 12.1 Electrons in atoms underneath "Applications and skills" it states "Calculation of the value of the first ionization energy from spectral data which gives the wavelength or frequency of the convergence limit". It is not that easy for teachers to find a good source of spectral data which gives the convergence limit. For example an internet search for the emission spectrum of sodium gives several images...
