Fig. 11

H- and K-band spectra of the FS CMa stars in Mc20 and Mc70. Unlike spectra in Figs. 4 and 5, the wavelength axes are not relative to the LSR reference frame, but taking each star at rest. The wavelength region beyond 2.195 μm has been omitted since it only shows a featureless continuum for both stars.
