Exclamation SEX output issues: HYBRID and CHI2PSF
Hi, we are using the new features of SExtractor to do model photometry with the latest version. What does FLUX_HYBIRD mean, or strictly what does HYBRID mean? And we saw the catalog and see that the CHI2_PSF is much smaller --> 0 (1e-8) than the CHI2_MODEL which is about 0.8-0.9 (this is normal). So is there any error about CHI2_PSF or something else I misunderstand?
