pPXF-SEW: A full-spectrum fitting method of stellar population Synthesis based on ‘’Equivalent Widths spectrum’’ without attenuation curve prior based on pPXF
Description
This pPXF-SEW package contains a Python implementation of the stellar population Synthesis based on Equivalent Widths spectrum (SEW) method and the Penalized PiXel-Fitting (pPXF) method. It uses full-spectrum fitting with SED to extract stellar and gas kinematics, the stellar population, as well as the dust attenuation curve of stars and galaxies, without a prior attenuation curve. The kinematics are derived from the pPXF method, while the stellar population and attenuation curve are derived from the SEW method.
The SEW method was described in Lu (2025).
The pPXF method was originally described in Cappellari & Emsellem (2004) and was substantially upgraded in subsequent years, particularly in Cappellari (2017).
Installation
