Hi Jing,

Thanks for your post here!

The power is normalized with respect to the excitation power.

The correct file format looks like below:

! File Format:


! L1:    N, M, U


! L2:    EXW1, EXW2, ..., EXWM   


! L3:    EMW1, P1, P2, ..., PM


! L4:    EMW2, P1, P2, ..., PM


! L2+N:  EMWN, P1, P2, ..., PM


!


! Where:


! N = Number of emission wavelengths


! M = Number of excitation wavelengths


! U = Wavelength unit flag (1=nm, ???)


! EXWi = Excitation wavelength i


! EMWi = Emission wavelength i


! Pi = Normalized power for EXWi
