Spectral index distributions between VLBA 22 and 43 GHz maps convolved with beams of different sizes. The blue lines are convolved with a circular beam of 1.2 × 1.2 mas, where the radius is the same as the major axis of the KaVA 22 GHz beam. The red lines are convolved with 0.8 × 0.8 mas, which is equal to the major axis of the VLBA 22 GHz beam. The distribution with the VLBA beam has a larger scattering than the distribution with the KaVA beam.
