That is a good question...I think I created these properties in order to use them in the ionization cross-section calculation here:

Perhaps it would be worth dropping this in the definitions, and putting the requirements on atomic number into the cross-section calculation directly? I could handle that, if so.

Yes, that's definitely the right move. Thanks for spotting this.
As a side note, I spoke with Peter Young about this issue of the range of Z for the cross-section calculation. He pointed out that in the Dere et al. 2007 (http://adsabs.harvard.edu/abs/2007A%26A...466..771D) paper, there's a note about the Fontes cross-sections being used for H-like ions of Carbon and above and using the FAC or BT scaling calculations for others. We should probably add a comment somewhere in that function that summarizes the justification in that paper.
