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
