Open source for atomic spectra raw data

Is anyone aware of a open source atomic spectra database? In particular I am looking for high resolution Na atomic emission which can be downloaded in csv or Excel. I am aware of NIST but I could not find a atomic spectrum. Secondly do they allow re-use of their figures? Thanks.




Based on your [previous question](https://chemistry.stackexchange.com/questions/130994/open-resource-for-spectroscopic-raw-data) and your comment above in lines of «NIST's policy to use published data may be fine» I question if your literature search included a visit at [NIST's Handbook of Basic Atomic Spectroscopic Data](https://www.nist.gov/pml/handbook-basic-atomic-spectroscopic-data).


In the case of [sodium](https://physics.nist.gov/PhysRefData/Handbook/Tables/sodiumtable1_a.htm), recorded lines for either air or vacuum are listed next to the data about *persistent lines*, and analogue data about the single ionized form. While not yet in a `.csv` format, copy-paste into an editor is eased because you may toggle between the output to be table-like [formatted](https://physics.nist.gov/PhysRefData/Handbook/Tables/sodiumtable2.htm) form, or [ASCII](https://physics.nist.gov/PhysRefData/Handbook/Tables/sodiumtable2_a.htm).


*Addition:*


An alternative could be to digitize emission spectra like the following:
