How to generate TPA spectra?

Dear All,
I have done TPA calculations for first 30 states. Is it possible to generate TPA spectra from output file of DALTON? If not, then how can we do it by own code? any references? How to startup this whole setup? Thanks in advance.

Before doing this, please try to know what the TPA spectrum is.
Then you will find that the Dalton has provided all things you want at the end of the output file.
Notes: there are many threads about TPA calculation in this forum.

I mean to say how to do gaussian or lorenzian fitting of data?

As I know, dalton cannot do this.
The expressions for gaussian or lorenzian fitting are simple. You can refer to the source code for fitting OPA, for example, Multiwfn source code.
