Fig. 3.
Image of the XMM-LSS field observations imaged with LOFAR at ∼150 MHz covering ∼27 deg2. The associated flux scale is shown on the right-hand side in mJy beam−1. The flux scale was chosen to range between -σcen and 10σcen, where σcen is the central rms of the image, which was determined to be 0.28 mJy beam−1.
