Metadata serving as basis for illustrations of Maximilian Hell's network in the book \"Maximilian Hell (1720-1792) and the Ends of Jesuit Science in Enlightenment Europe\" by Per Pippin Aspaas and László Kontler (Brill Academic Publishers, 2020)

The book \"Maximilian Hell (1720-1792) and the Ends of Jesuit Science in Enlightenment Europe\" by Per Pippin Aspaas and László Kontler (Brill Academic Publishers, 2020) includes several illustrations, including one visualization of Hell's surviving correspondence and another of sites of observation recorded in the appendices of the Ephemerides Astronomicae ad Meridianum Vindobonensem, edited by Hell. The task of producing these visualizations was commisioned to Katalin Pataki, PhD Candidate at Central European University in Budapest. She also enriched the metadata to accommodate it to the technical requirements of the visualization tools used.
