confusion in the Addion function to add multiple ions in the CRM about fac HOT 2 OPEN

using data files per ion is the correct way.

from fac.

I am running this command to include the Li I and Li II ions, and I gave the population densities in this way.

My ground state density of Li I varies like this for the given te and ne grid.

and the ground state density of Li II varies like this

But initially, I gave the ground state density of Li II as zero. How can I interpret this density now? Is it relative to the ground state density of Li I?
so in that case how can i find the actual density of ground state or any other states of Li II?
