2018: Gsolve

Reilly algorithm written in python 2, including a range of corrections to produce complete Bouguer anomalies.

2024: gSolve

Complete rewrite of Gsolve in python3 begins. Shift to api based and no gui. We chose version 5 as representing the evolution since 1970.

2026: gSolve

Released as open source code.
