SExtractor

If you're an astronomer or astrophysicist looking for a high-quality program that can build a catalog of objects from an astronomical image, then SExtractor (Source-Extractor) is a great choice for you. This software is specifically designed to reduce large-scale galaxy-survey data. However, it also performs exceptionally well on moderately crowded star fields too.

To be able to run SExtractor, you'll need to have the tinyfits library and CFITSIO installed on your computer. This software requires these libraries to provide its users with the best possible experience.

In the latest release of SExtractor, we've made some significant improvements to the sextractor-config.in file. We've added more adjustments and a new sextractor-config script to enhance the overall user experience. Additionally, we've also included a check for sizeof(int) in the configure.in file to ensure the software runs smoothly.

Overall, SExtractor is a top-notch software that can build an object catalog from an astronomical image with ease. It is tailored towards galaxy-survey data reduction but also works exceptionally well for crowded star fields. With the latest updates in the release, it's becoming even better and more compatible with different systems.
