It is not deliberate, good catch. You can replace it with fetch_hitran() ! Note 1 : fetch_hitemp() and fetch_exomol() could also be mentionned in the See Also section of fetch_hitran()...

It should probably be added here: https://github.com/radis/radis/blob/develop/radis/io/__init__.py (same for fetch_exomol)

Link to "column_2004" in the download-HITEMP example doesn't work https://radis.readthedocs.io/en/latest/auto_examples/plot_hitemp_OH_database.html#sphx-glr-auto-examples-plot-hitemp-oh-database-py

@arunavabasu-03 this one would be nice in Radis-App too ; you can add it in your proposal

If possible, wavelength & wavenumber scale should (both) use round numbers, just like this figure from the [ExoMol website](https://exomol.com/data/molecules/C2H2/12C2-1H2/aCeTY/) : 

Oh. We have that, or almost. There is an overpopulation key in calc_spectrum and Spectrum Factory. Divide your arbitrary vibrational population by the Boltzmann-distribution and you can give it directly...

Hello @Springder ! I do not have a MATLAB installation on my machine so I won't be able to work on that. Do you want to have a look at...

Hello! I listed all the methods above. They are all quite similar in terms of complexity. As discussed in #96 you will only have a problem in choosing what to...

1. Exactly for wunit. Currently it's only reading from harcoded set of values, either ~nm or ~cm. With that change we'll allow other wavelengths ("cm", "µm"), wavenumbers ("m-1") or even...

Ok perfect!!
