Transformation for ﹩{W}^{{\prime} }﹩ band. The left upper (lower) panel is the spectrum of F5III HD17918 (K7V Gl388), the orange, green and purple points are fluxes converted from 2MASS J, H and Ks; the red triangle is the AIRBT ﹩{W}^{{\prime} }﹩ flux. The right panel is ﹩J-{W}^{{\prime} }﹩ versus J − H color–color diagram for stars earlier than K7 from the IRTF spectral library, and the black line is a linear fit of it, as the transformation for ﹩{W}^{{\prime} }﹩ band.
