Convert air wavelengths to vacuum wavelengths

Description

Convert air wavelengths to vacuum wavelengths

Usage

airtovac(wave_air)

Arguments

wave_air

wavelength in Angstroms, scalar or vector

Details

Wavelengths are corrected for the index of refraction of air under standard conditions. Wavelength values below 2000 A will not be altered. Take care within 1 A of 2000 A. Uses relation of Ciddor (1996).

Value

wave_vac

Vacuum wavelength in Angstroms, same number of elements as wave_air
