The first release version of the OTSO tool. Basic functionality for cosmic ray propagation computations within the Earth's magnetosphere.
OTSO can perform computations of trajectories, effective cut-off rigidities, and asymptotic cones. For details on how to install and use please see the user manual contained within the repository. (Please note that OTSO has currently only been tested on Windows OS, details on how to download and use it on other OS will be added in the future.)
This release of OTSO is the version used within the initial article publication describing the tool and its uses ("A New Open-source Geomagnetosphere propagation tool (OTSO) and its applications")
OTSO is designed to be open-source and further releases are to come as the tool develops further.
