Begin of the transition to HelMod 4.0 modulator.

The new model includes the treatment of outer heliosphere and update simulation and forecast simulations from 2017 up to 2021.

Versione 3.5 will be available until the end of the transition to new model.

Developed a new  web calculator for Differential intensity integrated over the mission duration and forecast. This calculator integrates all the previous calculator introducing new features. It also includes  ISO 15390, DLR version and ISO 15390 . 

In Relevant Bibliography for HelMod and HelMod Results are available the preprint of newest Paper on electron solar modulation.

Forecast Modulator Now include also Carbon and Oxygen
