SEXTRACTOR MODULE.
This package contains the module for sextractor
.
- Author
Axel Guinot
- Parent module
mask_runner
- Input
Single-exposure single-CCD image, weight and flag files
- Output
SExtractor output catalogue
Description¶
This module calls the community standard source extraction software SExtractor [Bertin and Arnouts, 1996] to detect objects in the input images. All of the standard SExtractor options can be used by specifying the paths to the appropriate configuration files.
Post-processing steps can be carried out to add additional FITS HDUs to tile catalogues for each exposure, indicating the CCD number.
