Distribution of the SFR surface density values within the mass bin of log Σ_stellar [M_⊙ pc⁻²]≈8.5. Around 40% of the pixels are not detected in Σ_SFR and we observe a bimodality in the distribution. These non-detections have been highlighted in brown and moved to an artificial value (N/D). The vertical lines correspond to the derived average value for the three binning schemes in Fig. 2. The mean in log-space (green dashed line) matches the peak of the distribution of detections, while the mean in linear space (red and blue solid lines) correspond to the average SFR at this stellar mass surface density, including and excluding N/D, respectively.
