| Abstract: | C. B. Watts' charts of the marginal zone of the Moon have been put into the form of tables of rectangular co-ordinates of points along the contours. These co-ordinates were recorded automatically on paper tape and transferred, firstly to a magnetic tape, then secondly to an exchangeable-disc cartridge allowing random access to every chart. |
