This table enables to define the wavelengths that are used in the calculations.
---number---
It is the wavelength identifier.
---wavelength---
Wavelength value to be entered in microns.
---active---
The wavelength can be used in the calculations only if the related active check box is checked otherwise the wavelength is ignored. Note that one or all active wavelength(s) can be selected in the Options table for the calculations. A single wavelength is selected by its identifier.
---weight---
The weight is a positive number characterizing the importance of the wavelength. The weight is used in "spot diagram", "encircled energy", "PSF", "PSF_CROSS", "MTF", "best focus" and "transmitted flux" calculations (see tutorials relative to these calculations).
