1. When an external spectral samples file is supplied with units other than "microns", the HDF does not reflect the correct spectral samples. 2. When the "lwir" spectral window is supplied in the scene file, the console message from scene2hdf says the spectral range is 7.5 -> 12.5 microns, but it is actually 7.5 -> 14.0 microns in the HDF file.
