Spectral mode

What it is

Sets when the spectral correction runs. The formula it runs is chosen on the Model tab.

Typical values and how to get it

Leave it on automatic.

Values

Auto (CdTe) = auto (default): runs for cadmium telluride modules only · On = on: runs for every module; the air-mass modifier works for any technology, and Lee and Panchula needs the module's technology (it has a published set for each of the five) or coefficients given here · Off = off: never runs
