Fig. 1. (A and B) Radio source location as a function of the interstellar magnetic field (BISM) direction in (A) the HDP plane and (B) the GAL plane (with = 45°). The surface of the heliopause is shown from upwind with respect to the interstellar wind. The isocontours show the strength of the radial component of the interstellar magnetic field, Br, on the heliopause. The green band is the location of the radio sources (at Br = 0). The red arrows show the direction of BISM. (C and D) Same as (A) and (B) but converted to ecliptic coordinates for BISM in (C) the PPG (with = 30°) and (D) the GAL (with = 45°). The direction of the nose of the heliosphere (diamond) and the GAL (black line) are indicated for reference. The radio sources detected by V1 and V2 are shown as solid circles. Note that the colors are inverted from (C) to (D) because the interstellar magnetic direction was inverted from (A) to (B) (see red vectors in the insets).
