About:
SExtractor (Source Extractor) is a specialized astronomical tool designed to detect and measure sources from FITS format images. It performs source detection, photometry, and morphological measurements, outputting catalogs in formats like FITS-LDAC or ASCII. Its main value is high-performance batch processing for large-scale astronomical surveys.
Key Features:
  • Fast source detection and photometry
  • Morphological parameter measurement
  • Flexible configuration via parameter files
  • Supports multi-band processing
Use Cases:
  • Creating source catalogs for galaxy surveys
  • Measuring photometry for stellar fields
  • Generating inputs for shape measurement pipelines
Alternatives:
  • DAOFIND/IRAF – IRAF task for star finding; generally slower and less optimized for large surveys than SExtractor.
  • Photutils – Python-based photometry library; offers more modern integration but requires coding compared to SExtractor's standalone CLI.
