G.10 - Are the Tsyganenko Models included?¶

Answer¶

The external magnetic field models developed by N. A. Tsyganenko are available from https://geo.phys.spbu.ru/~tsyganenko/empirical-models/ under a GNU GPLv3 licence. This licence is incompatible with the UNILIB licence and so the models cannot be distributed with the UNILIB software.

It is not impossible for the user to integrate the Tsyganenko models themself into the UNILIB library for use within their own organisation. See the GNU GPL FAQ

Warning

The integration and distribution of the Tsyganenko models in UNILIB would infringe the terms of the UNILIB licence and the GPLv3 licence.

See the GNU GPL FAQ Combinations

Note

In the src/ext5xx subdirectory is a FORTRAN 90 file that provides for re-integration of the models, entitled tsyg.f90. If the user were to create a Tsyganenko subdirectory and place the TA16_RBF.f, TA_2015_B.f, TA_2015_N.f, TS04c.for, T01_01c.for, T96.for, T89d_dp.for, and T89d_sp.for files in this subdirectory, then their use in UNILIB is possible. The Makefile would also require changing to make use of the tsyg.f90 module instead of the tsyg_null.f90 module in the build.
