The VLA-COSMOS 3 GHz Large Project: Continuum data and source catalog release

Understand

We present the VLA-COSMOS 3 GHz Large Project based on 384 hours of observations with the Karl G.

• Jansky Very Large Array (VLA) at 3 GHz (10 cm) toward the two square degree Cosmic Evolution Survey (COSMOS) field.
• The final mosaic reaches a median rms of 2.3 uJy/beam over the two square degrees at an angular resolution of 0.75".
• To fully account for the spectral shape and resolution variations across the broad (2 GHz) band, we image all data with a multiscale, multifrequency synthesis algorithm.
