This was run through the Galaxy astronomy \"source-extractor\" tool (astroteam/source_extractor_astro_tool, built on SEP) on usegalaxy.eu via BioBlend, at tool defaults: detection threshold 1.5x the global background RMS, minimum area 5 pixels, deblending (nthresh 32, cont 0.005), background mesh 64x64. The tool returns a source catalog (position, flux, shape), a segmentation map and a sources overlay. The catalog and the radiance field were overlaid on the EU Natura 2000 polygons (EEA): the light-extent metric is the fraction of Po Delta pixels with radiance above 1 nW/cm^2/sr, and nearby settlements are catalog sources within ~10 km of the protected area.
