How do you describe the data used by Watson and the data used by Watson and Crick to determine the structure of DNA?

Watson and Crick used X-ray diffraction data gathered by Rosalind Franklin and Maurice Wilkins, as well as existing knowledge of chemical bonding in nucleotides, to determine the double-helix structure of DNA. This data provided key insights into the spatial arrangement of atoms in DNA molecules, leading to the landmark discovery of its structure in 1953.
