When you supply your radiance file to FLAASH, it prompts you to supply
scale factors as well. You can provide either a single value for all
bands or text file with an array of values (one for each band). To
convert from what you have to what you need, choose single value and
type "10". You don't need to mess with the scale factors stored in
the HDF--those are automatically applied by ENVI when you initially
open your file (they convert the stored integer data to radiance).
