Is the excitation spectra corrected by the lamp intensity in a Horiba Flourolog ou Nanolog spectrometer?

I used to correct the excitation spectra by dividing the raw spectra (usually called S1, or S2, or S1c, or S2c) to the spectra of lamp profile (usually shown by R). This way the excitation spectra...
