Labels used to identify the six modeling methods of this work.
| Modeling method label | Description | Corresponding source modeling technique |
|---|---|---|
| Sérsic+Shapelets | Sect. 3.2 | Concentric elliptical Sérsic profile and shapelets basis functions |
| Adaptive+Matérn | Sect. 3.3 | Adaptive Voronoi grid, regularized with a Matérn kernel |
| Cluster+Exp | Sect. 3.3 | Clustered adaptive Voronoi grid, regularized with an exponential kernel |
| Cluster+Exp+Lumweight | Sect. 3.3 | Similar to Cluster+Exp with regularization weighted by source luminosity |
| Sparsity+Wavelets | Sect. 3.4 | Cartesian grid, regularized with sparsity in wavelets space and non-negativity constraints |
| Correlated Field | Sect. 3.5 | Cartesian grid with Gaussian processes, regularized with a parametric power-spectrum |
Notes. These modeling methods mainly differ in their source modeling techniques, but share other differences (see Sect. 3 for details).
