Ku-band image (14.5 GHz, tracing ionized gas) of the W51 region produced with a combination of JVLA B and D array data using uniform weighting. The synthesized beam size is θFWHM ≈ 0.33″. The compact, circular region in the upper-right corner is IRS2, while the more diffuse bright region in the center is IRS1, marking the edge of the W51 Main shell. Compact sources are identified in Fig. 2.
