Full disc map of galaxy TNG 539333 O2 projection (upper) and TNG 294869 O1 projection (lower) for log₁₀[Σ_⋆/(M_⊙ pc⁻²)] (left), Z_⋆/Z_⊙ (middle), and t_⋆/Gyr (right) as an example of edge-on projection. From top to bottom: The top row shows the actual values for each property followed by the model created by a DNN algorithm on four Euclid bands, and the bottom row shows the residuals, where points in red (blue) represent pixels where the actual values are higher (lower) than those in the model. Histograms contained in the lower left or right corner of the residual maps show the distribution of error prediction (log₁₀y_i − log₁₀ ${\widehat{y}}_i$, where y_i is the actual i-th value, and ${\widehat{y}}_i$ is the predicted i-th value of the pixel), dashed lines mark the 16^th and 84^th percentile of the distribution.
