Mean wavelength.Defined as:λmean ≡ ∫λT(λ)dλ / ∫T(λ)dλwhere: T(λ) ≡ filter transmission Effective wavelength.Defined as:λeff ≡ ∫λT(λ)Vg(λ)dλ / ∫T(λ)Vg(λ)dλwhere: T(λ) ≡ filter transmission Vg(λ) ≡ Vega spectrum Pivot wavelength.Defined as:λ2piv ≡ ∫T(λ)dλ / ∫T(λ)dλ/λ2where: T(λ) ≡ filter transmission Full with at medium height. Defined as the difference between the two wavelengths for which filter transmission is half maximum Effective width.Defined as:Weff ≡ ∫T(λ)dλ / Max[T(λ)]where: T(λ) ≡ filter transmission. Equivalent to the horizontal size of a rectangle with height equal to maximum transmission and with the same area that the one covered by the filter transmission curve.
