VizieR Online Data Catalog: 3C 454.3 FeII, MgII & 3000Å measurements (Amaya-Almazan+, 2021)

The ground-based observational support of the Fermi Gamma-Ray Space Telescope at the University of Arizona has been monitoring 3C454.3 over the years as part of its program. Taking advantage of this great collection of data, in this work we used 529 optical spectra observed from 2009-2018 calibrated against the V-band magnitude. The redshift of this source (z=0.859) unlocks the near-UV region of the spectrum, allowing us to analyze the MgII λ2798 emission line and the UV FeII band, as well as to obtain the λ3000 continuum.
