PEC plotting NIST and ADF15

[ishikem]

I am using ColRadPy to model emission spectra of our plasma. The tutorial has a Warning, ' WARNING Note that wavelengths will not match NIST wavelengths unless the adf04 energy levels have been shifted to the NIST values. This generally hasn’t been done in the past so there are many adf04 files that don’t use NIST energy values.'

I was wondering, if this is still true and how will I know which data set is shifted to the NIST values and which have not. 
If I understand correctly, I can also use ADF15 to plot the emission spectra?

Thank you!
