Rms noise histogram of the pixels included in the released region. The solid line shows the cumulative function. The red dashed line indicates the rms value at the peak of the distribution (1.55 mJy beam⁻¹). The blue dashed line shows the position of the 50% percentile (median) at 1.63 mJy beam⁻¹. This means that half of the covered area (325 deg²) has a lower rms noise than that. The long tail of high rms noise values is due to bright sources in the field.
