Normalised NIR reflectance spectra of Jupiter irregular satellites, Himalia, Elara and Carme, obtained using the SpeX instrument on the NASA IRTF. The spectra are normalised to unity at 1.5 μm. The averaged spectrum used for linear spectral unmixing is also shown. Observational circumstances are listed in Table 1. Higher scatter in some wavelength ranges is due to incomplete telluric correction. The grey bands indicate the location of the telluric bands.
