Mean value and dispersion (blue area) of the noise level at different scales computed in 12 different regions on each image. The red lines are predictions using the formula in Casertano et al. (2000). The values of the noise on 1 pixel scales σ 1 are reported in each panel. Noise values are in erg s−1 cm−2 Å−1 for the images in the five filters (panels in the top five rows) and in erg s−1 cm−2 for the Hα emission map (bottom row).
