Peak (top) and integrated (bottom) flux distribution of GLOSTAR sources. The dashed blue and yellow lines in the upper panel delimit the 4σ_noise detection limit in areas free of extended emission (σ_noise ≃ 50μJy beam⁻¹) and for the nominal noise level of the D-configuration images (σ_noise ≃ 123μJy beam⁻¹). The red histogram in the upper panel shows the flux distribution of sources previously identified by CORNISH. The bin width is 0.1 dex.
