We have calculated the solar background rejection of the Mg atomic resonance filter operating at the b1 Fraunhofer wavelength (518.4 nm) as a function of the pressure-broadened filter linewidth. For pressure broadening induced by the noble gases the solar background rejection decreases from 93% at a 0.002-nm bandwidth to 82–84% at a 0.02-nm bandwidth. Solar background rejection was insensitive to buffer gas and was optimum for the noble gas with the smallest shift-to-broadening ratio.
