What will I learn?
Acquire hands-on skills in cosmography to chart the universe's large-scale structure with actual survey data. Master selecting sky areas, fetching and purifying catalogues, correcting for extinction, and implementing quality filters. Develop 2D and 3D visual maps, compute distances from redshift via solid cosmological principles, identify clusters, filaments, voids, and address uncertainties, biases, plus enhancements for upcoming surveys using dependable, repeatable tools.
