(a–c) The 2 GHz VLBI images of 1156+295. (d–f) The 8 GHz VLBI images of 1156+295. Relative right ascension and declination are plotted with tick mark spacings of 1 mas. Contour levels are 2%, 4%, 8%, 16%, 32%, and 64% of the peak brightness. Additional contour levels are −0.7%, 0.7%, and 1.2% for (a), (d), and (f); −0.55%, 0.55%, and 1% for (b); and −0.5%, 0.5%, and 1% for (c) and (e). The FWHMs in milliarcseconds and position angles of the restoring beams are 2.52 × 2.07 at −63°, 3.36 × 2.05 at −72°, 2.77 × 2.25 at −6°, 0.70 x 0.54 at −66°, 0.94 × 0.60 at −73°, and 0.73 × 0.59 at −10° for (a–f), respectively. The peak brightness levels are 1.67, 1.37, 1.15, 1.27, 1.34, and 1.13 Jy beam⁻¹, respectively. At least one negative contour is shown in each image. The centers of the fitted component positions are marked with asterisks.
