**B. Appendix**

On the subject of units, we start with the relationship of equivalence for the pressure of

$$\mathbf{1} \,\mathrm{dyn}/\mathrm{cm}^2 = \mathbf{0}.\mathbf{1} \,\mathrm{Pascal},\tag{25}$$

and considering that 1 fPa = 10�<sup>15</sup> Pa. We notice that [19] reached a value for the particle pressure pushing the surrounding LISM by the heliopause with a pressure intensity of 3.57 � 0.71�10�<sup>13</sup> Pa, and in its independent work, [31] proposed the observational value of 267 � 55 fPa. This is the same that 2.67 � 0.55�10�<sup>13</sup> Pa at heliopause crossing by V1. In a way agreeing within less than two standard deviations the two studies. Here we take advantage of the consistency of both studies to assume a pressure onto the LISM from the heliosphere of 300 � 50 fPa, which would correspond to an equilibration local interstellar magnetic field of 0.7 � 0.1 nT, which is about a much higher value of the average magnetic field of the very LISM of about 0.4 nT and which can simply be explained by our understanding of a medium which due to an anomalous electrons gas has as a consequence through the presence of magnetization work coupling to the gas pressure a medium permeability *μ* close to (½ � *¼) μ0. Equilibrium with μ!*

Burlaga et al. [47] show in V2 an '*expected*' **B-**field barrier at heliopause with a **B**field intensity of approximately 0.45 nT on the sheath side of the Heliopause. On the LISM side, the **B-**field is �0.7 nT. This implies a push by the sheath of about 500 fPa onto the interstellar medium, while at '*hp*' interface, the LISM **B-**field stresses equilibrate that push for a similar small value for the constitutive permeability of the medium *μ* � ½ *μ*<sup>0</sup> (see, e.g. [19])*.* This is consistent with our interpretation of the presence of magnetization work discussed in Section 3.4 with the help of more detailed studies from more advanced experimental quality plasma and equally good magnetic field data available from Ulysses and Wind SC.
