In this modern era of automation, we need to measure quantities.API documentation: airtovac2 and vactoair2 В¶ PyAstronomy.pyasl. Measurement of various quantities has been an integral part of our lives since ancient times.

In the IR, wavelength is commonly reported in microns (m ), and wavenumber is.This function is a wrapper around the RefractiveIndexAV class. We need to start with the following equation: 1/in which is the wavelength. Having units of cm-1, the wavenumber is the number of waves in cm and is proportional to. Another typical unit in the mid-infrared is the wavenumber. It seems that air wavelengths (or wavenumbers) are used, where vacuum wavenumbers.Converts wavelength in air into wavelength in vacuum.How do you convert from microns to wavenumbers and vice versa Wavelengths in the mid-infrared are typically expressed in micrometers, commonly called microns, where one micron is 10-6 meters.

Parameters:Refractive index from Peck and Reeder 1972. Parameters:Vacuum wavelength xc : float, optionalRefractive index according to Edlen 1953. The default isMethods airtovac(wvl)Convert air wavelength into wavelength in vacuum.Convert vacuum wavelength into wavelength in air.Refractive index given by Ciddor 1996. Mode : string, , optionalThe source for the wavelength conversion.

EXAMPLE: If the air wavelength is W = 6056.125 (a Krypton line), thenAIRTOVAC, W yields an vacuum wavelength of W = 6057.8019 METHOD: See Morton (Ap. WAVE is always converted toDouble precision upon return. 77, 119) CALLING SEQUENCE: AIRTOVAC, WAVE INPUT/OUTPUT: WAVE - Wavelength in Angstroms, scalar or vector WAVE should be input as air wavelength(s), it will beReturned as vacuum wavelength(s). Uses the IAU standard for conversion given in Morton(1991 Ap.J. Wavelength values below 2000 A will not beAltered.
