The following spectra were obtained using the HeNeAr source in the gold guider at the 2.1-m telescope. Slit 5 was used to achieve the best resolution and thus the identification of the maximum number of lines. Use of a wider slit will probably result in some blended lines, particularly in the J and H bands, and one will have to select unblended lines for the dispersion solution. The lamp continuum overwhelms any lines long of 2.5 microns; however, L and M band obervations may be calibrated by HeNeAr spectra at the same grating setting in the K or H filter, as appropriate. After performing the dispersion solution, the spectra are calibrated by multiplying the wavelength scale parameters in the header by the appropriate order factor. The wavelengths are given in vacuum Angstroms.
