May-01-2024:
Added a 'FHOST_5100' column, which is the host-to-total 
flux ratio at rest-frame 5100A. This host fraction is
estimated using a spectral PCA decomposition method, 
and is only performed for the z<1 subset of DR16Q. 
All other columns in the catalog remain the same, i.e., 
the original L5100 still includes potential host 
contribution. These FHOST_5100 values may be useful
if you want to study detailed AGN luminosity 
correlations, or to revise the single-epoch BH masses
based on L5100 and Hbeta width.
