fGaussianConvolSD: fGaussianConvolSD

In tommasojulitta/FieldSpectroscopyDP: R package for processing fieldspectroscopy data

Description

Function to compute the standard deviation of gaussian convolution on a specific spectral range

Usage

fGaussianConvolSD(Wl = Wl, Ref = Ref, CWl = CWl, FWHM = FWHM)

Arguments

Wl	numeric array: wavelenghts spectrometer to be deconvolved
Ref	numeric array: Reflectance
CWl	scalar: Central Wavelength
FWHM	scalar: Full-Width at Half Maximum of the central Wavelength

Value

numeric value: standard deviation of gaussian convolution on a specific spectral range

Examples

data("reflOO")


#Define center wavelength 


CWl<-600


#Define Full Width at Half Maximum 


FWHM<-8


#Extract SD of the convolved spectrum


res<-fGaussianConvolSD(Wl=reflOO$Wl, Ref=reflOO$Ref, CWl=CWl, FWHM=FWHM)


#plot results


plot(reflOO$Wl, reflOO$Ref, ylim=c(0,0.7),xlim=c(400,900), type="l",xlab = "Wl [nm]", ylab= "Reflectance [-]")


points(CWl, res, col="red")
