Main input parameters into the SExtractor configuration file.
| Parameters | Values |
|---|---|
| DETECT_MINAREA | 5 |
| DETECT_THRESH | 1.5σ |
| ANALYSIS_THRESH | 1.5σ |
| DEBLEND_NTHRESH | 32 |
| DEBLEND_MINCONT | 0.001 |
| BACK_SIZE | 64 |
| BACKFILTER_SIZE | 3 |
| PHOT_APERTURES | 1.5, 2, 3, 4, 16, 30, 45 3*FWHM, 8*FWHM |
Notes. This setup is established for the aims of our survey, i.e. to optimize the number of individual sources, especially faint, detected in all the photometric bands. DETECT_MINAREA and BACK_SIZE are expressed in pixels. The other quantities are dimensionless and defined on SExtractor documentation. We measured 9 PHOT_APERTURES, 7 are expressed in arcsecs (first row) and 2 as a function of the measured FWHM (second row).
