Line subtraction

The goal of the QED Atlas was to construct spectral energy distributions for the continuum emission from the AGN only. To that end, line emission (NLR and BLR) was removed simply by excluding selected ranges from the spectrophometry observations. However, photometry points were not adjusted. Spectrophotometry included ranges
