XRT soft X-ray images (0.3–10 keV) of the fields of 2PBC sources for which the corresponding soft X-ray counterpart is outside the 90% error BAT circle (continuous circle, in blue) and inside or at the edge of the 99% BAT error circle, indicated with dashed blue line. The counterpart identifications for which the optical spectra were acquired are indicated with arrows. Field sizes are 20′× 20′. In all cases, north is up and east to the left.
