(VLISM) Interstellar medium characteristics

Methavix

Hi all,
I am writing you because in my research I need to characterize the space environment for an interstellar flight from the Earth to Alpha Centauri (more exactly proxima centauri). So i need densities of atoms and ions (in terms of cm^-3), energies (MeV), magnetic field strength (nT),velocities and directions.

I read many papers about LISM or VLISM but the biggest problem for me is that some data are contradictory one another.
I subdivided the space between these two stars in different regions (e.g. from the Sun to the edge of the solar system, from the edge of the solar system to the termination shock, and so on) and for each region i woul like to yield average characteristics.
May anyone help me about this? i already have some data, as i said, but in many cases data coming from different authors are very different on another.

Thank you very much.
