Source Extractor detection.

write Image.sources and Image.peaks

Parameters:

  • threshold (float, optional) – threshold factor for which to consider pixel as potential sources, by default 1.5

  • n_stars (int, optional) – maximum number of stars to consider, by default None

  • min_separation (float, optional) – minimum separation between sources, by default 5.0. If less than that, close sources are merged

  • sort (bool, optional) – whether to sort stars coordinates from the highest to the lowest intensity, by default True
