Notes. (top) Summary of the definition of the scenarios to compute the present-time magnetic field in the thick shell of the Local Bubble. (Bottom) Values for the several parameters as defined in the text. In the top table, R_min and R_max are the inner and outer radius of the bubble shell as measured from the explosion center in (x_c, y_c, z_c). The left arrow (←) indicates that a surface is shifted to the coordinate system with center O := (x_sph, y_sph, z_sph) or $A : = (x_{c}^{P 20}, y_{c}^{P 20}, z_{c}^{P 20})$ $A: = \left( {x_c^{{\rm{P}}20},y_c^{{\rm{P}}20},z_c^{{\rm{P}}20}} \right)$ , where the superscript P20 denotes the values derived in Pelgrims et al. (2020) (see their Fig. 9 and Table 1).
