The ROSY ESR dating program

ROSY is a program that enables the calculation of average dose rates and age estimates in the ESR dating of tooth enamel, but has more general applicability to other situations involving layers of different media in planar geometry. The user has the freedom to chage a wide range of parameters, including the composition of each of the media. The latest Version, 1.4, includes consideration o gradients in the alpha track dose as well as in the beta dose, and several options for the input or computationof gamma and cosmic ray doses. The theoretical assumptions and procedures used in the ROSY calculations are described. We discuss the various user-controllable features of the program and the input and output of data, and aspects that may need particulat attention by users are highlighted. Possible improvements to the software in future Versions are discussed.
