2. Data and Basic Reductions: basic pipeline, source detection, PSF
3. Overview of Extended Source Processor:

GALWORKS, background removal, source parameterization, photometry, coordinate positions, source extraction

discrimination, basic metrics, multiple-star discrimination, color attribute, decision-tree classifiers

galaxies, bright-star artifacts, transient artifacts

catalog generation, basic results, completeness & reliability, source counts, angular size distribution, surface brightness, galaxy colors, ellipse fit parameters, comparison with previously catalogued galaxies
