*1  Approximate values for a 100 µm (for IR2 Modell 250 µm) standard slit. Other values for optional 50 µm or 250 µm slit.

*2  Measured with edge filter OG455 at 400 nm or silicon filter with 1200 nm edge at 1000 nm, relative to peak intensity of unweighted spectral data.

*3  Measured at a 150 nm interval to the left of the peak wavelength, relative to peak intensity of unweighted spectral data.
