How to output the spectra of stars, gas, cold dust and agn components separately？

I wanted to plot the contribution of each component when drawing the fit result, but I don't think I could find a simple way to do this. One way I find is use fsps source code but it is not convenience

There is not a simple way to do this at the moment. The best way is to make a prediction after turning off each of the different components using relevant parameters, and take the difference.
