I agree with Robin’s comment in #5 . You can easily add noise or worse systematic error from the reference.
I simply use the W lamp to remove the blaze from my echelles spectra and then rectify just those orders I wish to measure. The echelles has a more complex set of IR issues than the Lhires III.
