SFR2Lum: SFR to H[alpha] Luminosity

In asgr/ProSpect: Professional Spectral Analysis Package

SFR to H[alpha] Luminosity

Description

A best effort conversion betwen SFR and H[alpha] line luminsity. Mostly for use with emissionLines.

Usage

SFR2Lum(SFR = 1, lumscale = 21612724)

Arguments

SFR	Numeric scalar; star formation rate (Msol/yr).
lumscale	Numeric scalar; given by (1/7.9e-42) (Kennicutt, in erg/s) x 1e-7 (erg/s to Watt) x 2.61233e-27 (Watts to L[sol]) / 1.53 (Salpeter to Chabrier IMF conversion). Unless you have a very strong opinion on this scaling, the defaults is a reasonable best effort.

Details

Best effort SFR to H[alpha] luminosity conversion function.

Value

The H[alpha] line luminosity in Lsol.
