Package: alfa @ 2.2

Synopsis

Automated line fitting algorithm

Description

This package provides ALFA, which can identify and fit hundreds of lines in emission line spectra in just a few seconds with following features:

  • A population of synthetic spectra is generated using a reference line catalogue.

  • The goodness of fit for each synthetic spectrum is calculated. The best sets of parameters are retained and the rest discarded.

  • A new population of synthetic spectra is obtained by averaging pairs of the best performers.

  • A small fraction of the parameters of the lines in the new generation are randomly altered.

  • The process repeats until a good fit is obtained.
