Near-IR spectrophotometry in practice
Many nights of near-IR cross-dispersed grism observations with CASPIR (Mt Stromlo and Siding Spring Observatories), related to the AGB star follow-up program described elsewhere, have allowed us to collect a large number of spectra on bright stars of various spectral types, used as references in the correction for telluric absorption and in the flux calibration.
Ideally, such a reference star should have a perfectly known intrinsic flux distribution and as few spectral features as possible (otherwise, one can use two stars, one for the flux calibration, the other for the removal of telluric features, but that means spending even more observation time on reference objects). F-G type dwarves are relatively well modelled (e.g. Kurucz), but display many absorption lines. Low metallicity dwarves are somewhat easier to use in that respect. O-B type stars display essentially H and He lines (though not only), but these are often deep and broad (or in emission), and more importantly the energy distribution of O-B type stars is often affected by circumstellar or galactic extinction. O-B stars are also rarer than F-G dwarves. In all cases, the stellar features are blended with telluric features.

A few gzipped postscript files illustrate: The raw spectra in these figures still carry the signatures of instrument's response, which varied from one observational run to the other (especially when the instrument had been opened in between runs). The only reduction steps performed for these plots are: bias and dark subtraction, flatfield correction, wavelength calibration, extraction and sky subtraction.
