OMNI Data

New option added to download OMNI data to your personal version of OTSO. Data is stored alongside precomputed TSY01, TSY01S, and TSY04. Gaps are present in OMNI high resolution data, so some periods of time will require the user to find their own data source for a given time. However, most time from 1981 to present are available.

OTSO

Inclusion of option for pulling of space weather data from online sources (NOAA, WDC Kyoto, and GFZ-Potsdam).

OTSO

Inclusion of a makefile for ease of compilation. Makefile kindly provided by Dr. Christian Steigies of Keil University.

OTSO

Applied a fix to the particle.f95 file to correctly rotate particle trajectory when using the non-standard gaussian field.

OTSO

Hotfix for cutoff computations

OTSO

Updated version of OTSO that includes some bug fixing and extra functionality.

New Features Include

1. Bulk computation options so users don't need to do one computation at a time
2. Flight cutoff function added to compute the cutoff rigidities along a flight path (e.g. for aircraft, balloons, or low-orbit spacecraft)
3. Updated User Manual

OTSO

Quality of life improvements.
Instructions for installing on Linux and Mac have been added to the readme.
New 'Linux&Mac_OTSO_Compiler.sh' bash file has been added to automate compiling on Linux and Mac operating systems.

OTSO

Quality of life improvements.
Automated compilation via the "OTSOCompiler.cmd" batch file.
Unnecessary files and compilation artefacts were removed.
Updated user manual.
Updated and more detailed installation and compilation instructions.

OTSO

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.
