PL relations in the NIR and MIR for the five RR Lyrae variables with trigonometric parallaxes with HST+FGS from Benedict et al. (2011). There are four RRab type variables (filled circles) and one type RRc (open circle), which is plotted using its fundamentalized period (P_F, where ﹩\mathrm{log}({P}_{F})=\mathrm{log}({P}_{{FO}})+0.127﹩). The MIR data come from the CRRP and the NIR data are from 2MASS. Note the measurable slopes across the wavelength range and low intrinsic scatter (σ_λ ∼ 0.1 mag), which is indicated with the dashed lines about each fit.
