Hi Steven,

The apparent difference in the continuum between the two techniques is also of concern. This suggests either a non linearity in the process or alternatively a difference in the binning region or background subtraction. (The binning region should include the full width of the spectrum, including all the rows with spectrum data, to avoid distortion of the continuum shape due to changing focus along the spectrum and the background region should completely exclude the spectrum to avoid cross contamination)

Cheers
Robin
