gauss3func {rvmethod}

Three Gaussian Absorption Features

Description

This function returns three Gaussian absorption features, both with continuum 1.0 and each with a specified amplitude, center, and spread.

Usage

gauss3func(x, a1, a2, a3, mu1, mu2, mu3, sig1, sig2, sig3)

Arguments

x

the vector of values at which to evaluate

a1

the amplitude of the first feature

a2

the amplitude of the second feature

a3

the amplitude of the third feature

mu1

the center of the first feature

mu2

the center of the second feature

mu3

the center of the third feature

sig1

the spread of the first feature (must be greater than 0)

sig2

the spread of the second feature (must be greater than 0)

sig3

the spread of the third feature (must be greater than 0)

Value

vector of values of the three specified inverted Gaussians

Examples

x = seq(5000, 5003, length.out=200)
y = gauss3func(x, 0.3, 0.5, 0.4, 5001.5, 5002, 5000.4, 0.1, 0.1, 0.13)
