The files accessed by this page do not extend to wavelengths below 5 microns. See the near-infrared atmospheric transmission page for plots of the transmission at shorter wavelengths.
The number of values returned is independent of the resolution, and reflects the wavelength sampling of the originial ATRAN models. When lower resolutions are requested the values are convolved with a gaussian of the appropriate width. In fact the wavelength resolution requested in microns (or the value calculated from the resolution given as wavelength/sampling interval) is assumed to be the sigma value for the gaussian function used in the convolution. Thus the line FWHM from the convolution will be about 2.35 times the wavelength resolution specified.
