Overview¶
FastSpecFit
leverages our understanding of galaxies and quasars to build a
physical model of their observed-frame optical spectra and UV/optical/IR
spectral energy distributions (SEDs).
Simple Stellar Population Templates¶
Document the templates, physical properties, etc.
Modeling the Stellar Continuum¶
Initial line-sigma estimation.
Finding significant lines; masking.
Velocity dispersion (with criteria).
Aperture correction.
Smooth continuum correction.
No-photometry and photometry-only modes.
K-Corrections and Rest-Frame Photometry¶
K-corrections.
Default cosmology.
If the inverse variance on a given absolutely magnitude is zero it means that the absolute magnitude was derived from synthesized photometry based on the best-fitting model (i.e., use with care).
Modeling the Emission Lines¶
Line-fitting (broad, narrow).
Continuum, EWs, upper limits, etc.
Planned Improvements¶
Additional QSO templates.
